Your 350 will do whatever you tell it to do, up to 720x480 (NTSC).  
Personally I'd go with the max resolution, you can always transcode  
to mpeg4 to save space later.

How do you feel the units compare. I'm interested in the difference  
as well, but I don't know how to differentiate between encoding  
artifacts from the Plextor and artifacts from Myth's mpeg4 playback.

Comparing live TV from the Plextor and playback of PVR recordings  
that have been transcoded to mpeg4 should eliminate the playback  
factor from the equation at least partially. So far the Plextor  
recordings seem marginally better, but both are quite watchable. I  
need to tweak the mpeg4 transcoding parameters more to see if I can  
improve them.
