I regularly encode SD I-frame only MPEG2 files for broadcast distribution
via upload to DGFastchannel. I have never experienced a problem.
I myself have never experienced an issue with the MPEG2 files produced by PP.
But, if you think there is a bug in the software, you can report it using the link below.
Can you please be more specific. Please tell us the source material, size, framerate, encoding etc.
Then what type of MPEG2 file are you trying to create? A simple DVD compliant, 720x480 29.97 7mb file? OR some other viariant
What type of computer, memory , hardisks?
CS5 produces flawless mpeg 2 files for me any time I have had to do it.
