First off, try these directions, if you haven't already: http://www.rsmas.miami.edu/personal/angel/mythtv/air2pc-howto.html They were the foundation i started with to make mine work (FC3, Air2PC, Myth 0.17) I ran into the permissions thing as well, and once I got the DVB driver loading correctly at boot, they all went away. Second, working with HD channels is REALLY messed up right now. Badly. Even in the latest CVS. It took me most of (2) days to get mine right.. Here's what turns out the be the recipe to success, at least for me. 1. Run the channel search in the mythv-setup program (also found in /usr/src/mythtv/setup/setup if you checked out from CVS and put it in /usr/src). Let it add ALL the channels it finds. This is the only place you're going to get ASTC information the backend needs to tune. 2. Go create an HD specific profile on Zap2IT for the channels you want to use. Map that profile to the HD card. Run mythfilldatabase to get some data in. 3. Open the channel editor in mythweb, and start carving up. Important things are XMLID's (for program data) ATSC PID information. I did a little bit in phpmysql as well, but when I was done I'd combined all the right things from the channel search and zap2it. Basically I took the ATSC info, and moved it into the Zap2it channel entries, and then made all my "searched" channels not visible. if you remove a channel from either listing, it gets added back, either when you run mythfilldatabase, or run a channel search again, so it's better to leave it there, but not visible. Let me know how this goes, I'm happy to help a fellow air2pc'r.
