I though lots (most?) folks where using a PVR-350 because of the exceptional 
TV out quality?  Maybe I just got that impression because I see so much talk 
of the 350 on the board?

But doesn't transcoding to MPEG4 defeat the purpose of having my PVR-350 card?  
Now when I go to play the movie back is it not going to have  to do some sort 
of software CPU intense playback?

Probably... but then again Myth 0.14 is the first release to support PIP with 
a PVR-350 card so I didn't expect it to be perfect first time round.  
Remember I wasn't complaining about Myth.  Just pointing out a few issues I'd 
noticed and saying why I personally didn't think it should be released at 
version 1.

I to built this particular box from scratch specifically for Myth.  I joined 
this list before purchasing a thing and everyone was raving about the PVR-350 
and good the TV out quality was.  So that's why I picked it.  Prior to this 
list I'd never even heard of the PVR-350.  What TV out card are people using 
that's stable?  How much of a quality loss are they taking?  I don't see how 
a tremendous quality loss would be desirable?

When I post errors I get I do indeed try and be as detailed as I can.  I'm not 
sure what a backtrace is though?

I haven't and I think I will at some point.  Although I don't think my OS is 
unstable but testing something else on a test drive never hurt.

To sum up everything I pointed out probably most of my issues as you pointed 
out are related to the pvr-350 and are probably more suited to ivtv driver 

Please don't think I'm bashing Myth in anyway.  I should probably point out a 
very great and stable side of it I make good use of for those browsing the 
archives.  I have it setup to record all my favorite shows and that's exactly 
what it does.  I come down to my basement and waiting for me are tons of my 
favorite shows it's being quietly recording while I sleep or go to work.  I 
grab my remote and enjoy.  Zipping through the commercials is especially 
pleasing.  I also really enjoy the weather module and love just popping up 
the local weather forcast and map at any time I please.

Thanks guys
