One of the annoyances of my HD receiver is that it NEVER refreshes PSIP information. So if something major is changed, or a new subchannel added, it doesn't know about it. On the plus side, as long as the *base* signal structure is the same, it continues to work even if they mess up something minor.

Based on old PSIP I'm still getting sound and picture, but tonight I'm getting pretty horrible reception - no more than 69% and it's constantly breaking up and disappearing. I'll try again tomorrow.
