Groovy! I also found several detailed instructions on getting X running on the 350. 
Now I can say bye-bye to the Radeon 7000 and just use the VGA that's onboard the 
motherboard during setup. That'll leave another slot for capture cards. UPS just 
showed up with my PVR-350...

I hope this works. Replacing the DVD player in the AV shelving is a primary goal for me.

Ooh, good idea! Added to Future Project list.

Duh! I forgot about that scenario. Note to self - plan to get another tuner.

I'm glad it's that easy.

Too bad that's not working. But since it's easy to add cards, it sounds like I can 
afford to wait until support for that card settles out.

Right now I'm going to go with just the scenario you describe: everything on this one 
box. Already have a 'house server' in the garage providing net connection, etc. I 
hope to upgrade it at some point and make it the backend with a bunch of raided, 
hot-swap storage. Maybe do video capture too on it. Your idea to do diskless 
workstations is a good one. Might even be able to do something fanless!

Just did the ATrpms install of mythtv-suite. That's a lot of packages! But no errors, 
thankfully. We'll see how the PVR-350 works now.
