I don't believe it supports ATSC resolutions, but I could be mistaken. 
Whether that's an implementation issue or a sheer processing power 
issue, I don't know.

Someone else will have to chime in here for a definitive answer, but 
I'm about 99% certain the PVR-350 can't do a lick with an ATSC stream, 
and probably never will. One of the issues is that to use the 350's 
decoder, you have to use its video out, which is limited to NTSC/PAL, 
so you wouldn't ever be able to output a High-Def resolution anyhow.
