MPEG4 video does NOT work, and after two attempts plus a week of waiting, the manufacturer's technical support has no idea how to make it work.I asked specifically about what video format to code and which ISO version to burn. The only thing they could tell me is that DivX4 & XviD specifically won't work, but they have no idea what MP4 formats >will< work.The reason why this rates two stars instead of one is the price that I found ($70), burned DVDs >do< work (all DVD +/-RW that I tried), and as an added (unadvertised) bonus, it will read both NTSC and PAL video.As a side note, the A/V input cable is (to my knowledge) non-standard, using a single, three-wire 3.5mm mini-plug. By contrast, I also have an older (1st generation) portable DVD where the A/V cable split into two 3.5mm mini-plugs (a two-wire standard audio and a single-wire video) which allowed (now) standard cables to be used as replacements in case the included cable was lost or destroyed.
