I have a Mediagate MG-35 with firmware 1.4.x (different ones) and use MediaCoder 0.5.1 to convert DVD's to MPEG4. I have tried different frame rates and sizes, but can't get any MPEG4's files to play on this unit without playback issues. Other video formats work fine. MPEG4 videos playback fine on my XP pc. Any ideas on what Mpeg4 settings I should use?????
