Dear all, have just burned two movies to DVD-R using the A05 and Infimum media at 4X. Both movies worked perfectly on the PS2, menus etc. but only one worked on the XBOX. I had heard rumours that the XBOX wasn't compatible with writable media, but it played my first movie fine( original DVD under 4 Gig) but the second I had re-encoded/muxed with ReMpeg/IfoEdit and burned using Nero and just can't figure out what's gone wrong? Any suggestions greatly appreciated . Best Wishes .
