I assume they want ATSC-HDTV wrapped in DV format,
right? Just saying DTV implies it could be
NTSC type format.
Correct me if I am wrong, but I think they want
something recorded with a HiPix or WinTV-HD card
and then converted with "DVspoof" to DV format and
written onto camcorder tape.
Suggestion: tell these guys that they should
buy a HiPix card and record something themselves.
If they are going to make a proper product
they need to be able to have their own source
for test streams.
