I've found basically the opposite.  Nvidia may be binary but it 
generally works and supports additional features that ATI lacks like 
XvMC hardware assisted HDTV playback.

Well, bugs and missing features are only really relevant if they affect 
that you're doing.  I'm not sure what combination of drivers you were 
using or what distribution you're on.  The FC4 packages from atrpms.net, 
etc. seem pretty solid for me with my PVR-500, PVR-150, and HDTV QAM 
card.  As with anything, Myth is only as stable as the underlying OS and 
drivers.  Given the newness of IVTV 0.6 and 2.6.16, I'm not sure you can 
really expect increased stability over something like 2.6.15 and IVTV 0.4.4
