Yep, if you add to that the occasional "tinny audio" ... that about
describes the status of mythtv/pvr-350 tv-out stuff.

I must say that I still love my 350 tv-out quality and I'm really
looking forward to the next ivtv driver...

As far as what we (non-programmers) can do...  Just keep looking out for
bugs and try to pinpoint them for someone else to fix them.
