I am working with a collegue in the UK, sending MPEG-2 files (NTSC and PAL) compressed with Sorenson Squeeze 4.5. When he imports the files in DVDSP, he sees a white screen, and gets no audio. When I review the MPEG-2 files here in WMP, they look fine, and have audio. Sounds like a codec issue to me, but that would not cover the lack of audio. Suggestions?
