I have some copied dvd's that play on a mates standalone machine. they last around 90 mins. When I open the dvd in "my computer" the files are called "mpeggav, EXT, segment" etc. I thought to work it all needed to be in a "VIDEO_TS" folder. It also says the total size of the disc is 11.6meg, which seems very small to me. When I play it all I get is a few still photos. I have put all the folders in one and called it VIDEO_TS and loaded it into my burning program. When I did this the total size went to 622meg, which still seems small. It burned fine but then on play-back it said "unsurported format" Right. I Hope that was all clear. In short does anyone one know how I can get these to work or rename the files so I can copy them? Any help would be great!
