[mythtv-users] MythTV - Xbox - Xebian - black screen - bad

[Mark Knecht]

Scott,
   Unfortunately I'm told this morning that the screen is still black
or possibly dark grey. They're not sure if it's different from
yesterday but clearly it's not a MythTV menu when they first turn the
TV on. They are still having to hit a remote control key to get to the
point where they see anything.

   Any other ideas?

Thanks,
Mark
