Just play the video file in any pc based dvd playback software such as
PowerDVD and show info. I bet that most all of the recorders out there do drop
to mpeg 1 format for 4 hour plus. If not , then at the very least its dropping
the resolution from 720x480 to 320x240 and dropping the bitrate down very low
to near VCD quality.
