I had to call 3 times, finally spoke to level 2 tech supoort, they sent the update, seems to be working fine, got all my channels back, hasn't locked, and it's been over 12 hours. Call display now works, interactive TV does something, but I'm not subscribed so I don't know if it is working properly. It still won't tell my vcr to record, even though it's the right code (works on the remote just not from the receiver).
I hope this firmware will be more stable, the guide download seems a little quirky, but it may not have updated since I didn't turn the unit off, I'll double check my update time.
