[Libav-user] Convert MP4 1280x720 to MPG 1280x720

[Thomas H]

Hello Michael

Thanks for the link.

I have a DVD Burner program that only accepts avi, dvr_ms, mpg, mpeg,
mpv, wmv, or asf files. I am trying to convert mp4 files to one of
those.
While I can convert to mpg, the mpg file is pixelated, less quality
than the original when I compare them using VLC Media Player.

Regards
Thomas
