MCE remote delete button & slideshow

[surtr]

Hey everyone -

I'm a recent convert from SageTV. So far I'm liking 7MC a lot. My setup is simple: 7MC 64 bit, Xbox 360 slim, HDHomeRun Prime on Comcast.

2 questions that I've been unable to find answers for:

1. Is there any way to map a "delete" command to an MCE remote so that from the xbox I can click delete on a TV show name (grouping of all the episodes) and have it delete everything in there? Just like selecting and hitting delete in MC on the 7MC machine.

2. Is there any way to have a slide show start up when the xbox media center has been idle for a while? Currently it just dims way down.

Thanks!
