@gtreneman: You could call the cable company and ask them to check it out. They can test it and correct any deficiencies they find. Make sure they scan all of the frequencies for signal strength and SNR.
Before you do that though, make sure all of your connections are tight (using a pair of pliers and/or a small wrench). Don't just tighten them "finger tight" because that's not good enough to ensure a good ground for the cable's shield. You may even want to remove the wall plate to be certain that the cable in the wall is tightly-connected to the male/male coupler in the wall plate.
Also, make sure your cables are all RG6, not RG59. Obviously, you can't control what's in the wall... but you can make sure that the cables outside the wall are the right type.
A signal strength of -9dB is borderline... and may not be enough if the SNR is lower than 35dB.

I've posted http://www.thegreenbutton.tv/forums/vie ... 538#p29538 too, but just ran across this one. I've been having the recurring no tv signal problem myself.
Comcast just came out and we determined that the low signal levels I am showing are occurring between the end of the cable and the PCI card. Comcast installed a +7db signal booster on ONLY the cable going into my PC (+10 amp and a -3 pad) so that upon testing, he showed unacceptably high (+16.8db) signal levels, while the infinitv shows, finally, really healthy signal levels.
The tech was totally amazed to think that I'm losing 600+ feet of cabling's worth of attenuation just on the hardware and tail connector but unless there's a problem in the ceton hardware with the reporting of the signal strength, that's what's happening.
Anyway, the signal strength is completely outside the range of concerns at this point. I can either boost it so it looks right on the card or I can leave it be so it looks right at the cable termination. The big question is whether or not the problems will reappear over the course of the day. Most of the time, I get the "No tuner available to satisfy current request" (which requires a reboot to resolve) or "No TV Signal" (which often, though not always resolves itself) errors after 3 to 6 hours. With this tech visit, I think it's safe to say with absolute certainty that I'm not suffering from low signal levels anywhere, at all.
The card IS positioned next to the PSU in the case, but I'd be very surprised if this was the problem. If it were, my SNR would be lower,I think, because I'd have a very high noise level, if I understand that bit of the equation correctly.
Someone is going to think of temps here, and so far I've not seen them go out of range. Currently in the 52-55 C range on all 4 tuners.
If anyone has any advice or comments, I'd love to hear! Thanks in advance!

Just as an update for the public record, Ceton walked me through a ton of steps, none helped or had any impact on the problem whatsoever.
Now they have simply stopped responding for the past day and a half... and counting. (Whereas I WAS getting responses within a few hours, tops.) I think maybe they don't have any idea what the problem is, and just decide to ignore tickets they can't resolve. Perhaps to avoid being held responsible for the returns on defective merchandise? Who knows. Anyway, this has been an unfortunate experience with a company I thought would do better. I'm going to try the HD HomeRun Prime instead but I guess I'd have to say... caveat emptor!

To add to the collective information, as I've noted in my main thread about this issue, there is an excessive flood of UPnP traffic being initiated by "System Process" trying to connect to 192.168.200.1 on incrementally increasing port numbers. Thousands of attempts are stuck in "TIME_WAIT". I used TCPView for Windows to sniff these connections and gather a report.
The "unconnected TCP endpoints" look like this:

There are thousands of them. If there's any problem with excessive UPnP traffic, it's right here, and it's heading for 192.168.200.1 which I'm sure you all know is the Ceton hardware. So don't let them blame you, or your setup, software, etc. Check this out and I could just about guarantee everyone is having the same thing.[System Process] 0 TCP evilolive-pc.local icslap 192.168.200.1 32769 TIME_WAIT

@evilone
I'm not having the same issue at all. I do get a no tv signal on occasion but not very often. I used to get them frequently, but when I upgraded to the beta firmware, the infiniTV is now able to tune to a channel much more quickly almost completely eliminating no tv signal available message. I haven't missed a show to record yet even though I get that warning from media center everyonce in a great while.
I know how frustrating it can be when something doesn't work and your trying to trouble shoot. Have you asked Ceton to remote into your htpc? Maybe they might be able to see something that you're not seeing?
I just wanted to update my post here: I saw your post in the other thread that in your particular case you found the culprit of your udpnp being flooded with traffic. Glad to hear that removing MCE Buddy solved the problem & that the infiniTV is working now.
