Running PSP v3.03. Clonedvd burning to mpeg4 works fine. Issue is that I can't burn in AVC format. Tried both clonedvd options (firmward versions 2.6 & 3.03). I'm using the correct file structure and names. For example MP_ROOT\100ANV01\MAQ10002.mp4 In my PSP it shows the file but just calls it unsupported format. Any suggestions? Just burning straight from the original movie. I know the resulting file works as I can play and watch it in quicktime, just PSP don't like it
