   My next experiment to record a digital 480i signal and see how
>> that plays back as opposed to the pvr250 480i recording.

I was able to record a digital 480i signal last night, no joy.  The 
results were the same.  It seems almost as if the picture is being 
de-interlaced and them played back on an screen or being de-interlaced 
twice.  De-interlacing is disabled.  I played back some non-interlaced 
content using mplayer and got the same visual artifacts.  I also played 
back the 480i digital recordings and from the pvr250.  They all played 
the same.  Like I said the gui looks perfect, no artifacts nice and 
crisp.  Just can't seem to play video in that mode.  Has anyone had any 
luck playing back 480i content in a 480i mode via DVI?  I have taken a 
picure of what the artifacts look like, didn't attach because I'm sure 
it would violate some rule of posting.  If anyone is interested I can 
email the picture.

It's not, it was just one of the modes being returned.  I double checked.
