My friend burned a whole bunch of video files onto a DVD-R disc (like over 20 of .avi or .rmvb files), but when I tried to watch them using my DVD-ROM/CD-RW combo drive, it is extremely slow. The drive constantly seems to be reading the disc and I can finally see the filenames in the disc after like 5 minutes (from "my computer"). Then when I tried to click on one of the .rmvb files to get RealPlayer to play it, it again took 5 minutes or so to open and then it just stops after playing for 20 seconds.
What could be the problem? I'm using WinXP and I know my drive plays video DVDs (the real ones) without any problem. Also my realplayer plays .rmvb files on hard disk without problem. Thanks for any advice.
