It is fast and easy to convert videos to Xvid4, MP3 audio & 480 pixel height. (FYI, I typically use Xvid4 with quantizer 4, single pass. MP3 Joint Audio 128 kbit, and whatever horizontal resolution matches with 480 vertical)
The issue I have is the complete lack of video listing when playing off of an SD card. Would it really have been that difficult to add a file name listing menu?
