Incorrect mapping

[philipt95148]

I have a weird mapping situation here.
Normally 27.4 is LAFF and 43.4 is BOUNCE but it’s now reversed. See pic attached.
When I record 43.4 now, it’s recording 27.4 and vice versa.
I tried reinstalling WMC, delete eHome files, rescanning TV signal but problem is not solved.
Does anyone have this problem or can point me in another direction to solve this please?

I'm guessing that both main channels have the other channel in their sources. You need to edit the sources for each channel and remove the check mark from any source that is not the correct channel.

Right click on the channel in the guide→edit channel→edit sources→uncheck the tuners that you don't want to use for that channel.

When you view a channels sources, you will only see 4 of them on the screen at a time, you may have to scroll to see all of them.

I didn't know I can edit channels from the guide. I always use the Tasks, which is really slow.
Thanks

[philipt95148]

I didn't know that I can change it! Thanks!

I use a 4 tuners Hauppage and both channels are showing that they use the same 4 Hauppage tuners. see pics attached.
It's weird that this error only occurred on these two channels, the rest of the TV guide is OK.

And this happened only recently when after a download, the TV guide went blank and came back (I think after I restart the HTPC, not 100% sure how it came back) but after that, these 2 channels show the reverse mapping.
It even came through on Live TV with the channel number and the channel name which of course is wrong, but TV guide in WMC continues to show the original channel number and name, this makes recording impossible!
I wonder if this is somewhere in the EPG download or WMC?

in the pic, you'll see that WMC shows 46.4 listed correctly as KRNSCD4 but TV broadcast is KRENDT4 !

You show the sources for 27.4 as being freq 26.4 which wikipedia says is correct for 27.4 what is the source list for 46.4? Wikipedia thinks it should be 18.4 is that the case? One possibility is ithat there has been a local restack and the broadcasters have shuffled things around.

[philipt95148]

It shows 18.4 as attached.
The weird thing is that WMC shows the correct channel names and numbers but the broadcast is reversed and Zap2It shows it has not been changed.

[stuartm]

I assume if you view with a TV (not via WMC) that the same channels show the correct broadcasts? If so either somehow WMC is confused or perhaps the broadcasters swapped channels. If your TV (without WMC) has the feature of showing you the actual physical channel it is tuning for a virtual channel you can check to see if the TV tunes the physical channel that matches the one WMC says it is using.

[philipt95148]

TV shows the same mix up.
Zap2It guide is for zip code 89521.
I tried a few different zip code to see if I can find one that swaps the broadcast around but no luck.

According to rabbitears.info, this is what it should be:

Code: Select all

Display      Physical     
Channel      Channel    Network
27.4         26.4       Laff
46.4         18.4       Bounce

https://www.rabbitears.info/market.php? ... 93#station

Which seems to match up with what WMC has, so everything appears correct.

I suppose there could have been a recent change in which they swapped what network is on what channel, perhaps by accident, perhaps on purpose. In any case, this is something that needs to be fixed by the networks themselves, or by the guide provider (if it is a purposeful swap of the channels for the networks).

You can manually change what network is associated with each channel in the EPG123 client tool if you want.

[philipt95148]

I’m not using EPG123 but EPG.
Can I swap the physical channel over and would it work?
It’s weird that WMC shows the correct channel names and numbers but the broadcast is swapped just like live Tv.

It looks like you said that even on a regular ATSC TV set you saw the networks for the two channels were swapped. This indicates to me that for some reason they swapped channels (intentionally or unintentionally).

If this was intentional, then the ultimate fix is to have the guide listings updated so that they reflect the correct channel with the correct programming. If it was not intentional, then you should contact the stations themselves to fix it, or at least find out what is happening.

As a temporary fix, you can do the swap I mentioned without EPG123 and instead use WMC.

Just go in to the channel guide and highlight the channel you want to change (the logo/call letters to the left of the guide). Then right-click, or press the "info" button on the remote to bring up the pop-up menu, then select "Edit channel".

Select "Edit Listings".

Scroll down the list and select the listings for the channel you want to appear on this channel (make sure you select the HD listings or the SD listings as appropriate).

Do the same for the other channel.

After this, the guide should show the correct listings associated with each channel.

Just a note, a poorly advertised fact is you don't need to use epg123 for your guide data in order to be able to use the client. The client can be used with any WMC from Win7 and up.

Changing the numbers in WMC didn’t do anything.
I looked further and found the mapping error, channel 27.4 is mapped to 46.4 which is Bounce.
What I don’t know is how to fix this.
I have asked the same question in the EPG forum.
Hopefully someone may be able to help me out.

That picture is too small for me to read.

How many tuners do you have?

The picture you posted earlier was showing that for channel 27.4, at least one of the tuners (tuner 3) was set to 26.4. Did you check all 4 sources for channel 27.4 to make sure they were all set to 26.4? If some of those are set to 46.4, then you need to uncheck them. You can enable the "Show Preview" option on the left side and WMC will show the channel in the background as you highlight each source.

Perhaps you are saying that you renumbered your channels so that 46.4 was renamed to 27.4? Not sure how any of this makes any sense if your completely non-WMC stand-alone ATSC TV using it's internal tuner also has the channels swapped.

[philipt95148]

Here's a larger pic, hopefully you can see this.
It seems that the XML conversion got corrupted and mapped 2.4 to 46.4!
I checked the Zap2IT download and it was fine with the channel names and numbers, it's only in the XML conversion that it got transposed one over the other.
Should I delete all versions of eHome and XML and retry?
I have Hauppage 4 tuners.

I don't really know enough about the MXF file to know what that is saying. But again, I have to ask, did you not say that the same problem exists for a regular stand-alone TV with it's own ATSC tuner?

[garyan2]

That is not an mxf file for guide data. Looks like it is an export... where did it come from?

My knowledge of this is limited to just follow instructions on how to download TV guide using EPG Collector software.
1. I run a batch file that download the guide into an MXF file
2. Then a second process export that MXF file into WMC. I guess that’s the WMC export file that you see.

Usually it’s a 1 for 1 import for the channels but somehow, somewhere something got corrupted and transposed the channels 27.4 to 46.4.

This happened around November when I saw the TV guide went blank and then came back. After that the channels got messed up like you see. But it only happened to those 2 channels!

I tried to restore my system to a date before November, uninstalled EPG collector , uninstalled WMC , deleted eHome folder and reinstalled everything but the error persists.

Yes it does. I don’t know how either.

[stuartm]

That pretty much implies it's not a problem with your mxf file rather it's something the broadcasters have done. You might try a rescan on your TV to see if that changes anything there.
