I think it should, from what I've read in its documentation and sources.
The TV norm seems to be only set by the inversion field in the
channels.conf entry, so you have to specify your "I0" (take care of the
syntax, I don't know if it matters if it's before or after "C0". You
should also set "Frames per GOP" in the setup menu or setup.conf entry
of the pvrinput plugin to 15 for NTSC (for PAL I think it's 12). And I
also think I found a bug by grepping after tv norm and stuff in the
source, please also apply attached patch, I think the frame size was
always set to 720x576 which can never be NTSC.
I also guess you patched your VDR for NTSC, so maybe it just can't
playback your pvrinput stream if it's looking like you described, be it
live or recorded, as it seems to be PAL...
Try these, maybe it helps, but I can't guarantee, as I'm not the author
of pvrinput, and I also can't test with NTSC.
