[Cialug] MythTV HD tuner?

I figured that would be the case. I don't know that I need to encode 
full 1080p content unless it was something special, would probably do 
720p or less most of the time.

For my MythTV server, I was thinking of upgrading an existing PC chassis 
with a decent Core2Duo setup.

For playback, I'd either use my PS3 (not sure how user friendly that is 
yet... last time I checked into it nobody had figured out how to make 
the DLNA media servers put meaningful names on the encoded files), or my 
Shuttle with an AMD X2 processor. I'd hope that either of those would be 
powerful enough.

I'm just in the investigation phase. I'm not against having to do some 
hacking along the way, but I want it to work when I'm done. I'll 
probably also look into appliances or getting a DVR from my provider too.
