Hannspree I-inc 7 Portable Made By Hannsg

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 US), 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.
