Hello I've a DVD-R disk with many M2TS files on it from a Panasonic hd-camcorder (AVCHD). In a Windows Vista computer I can see the m2ts-files and play them with VLC. In a Windows-XP-SP3 computer I cannot see anything. The computer cannot recognize the disk. Why? What must I do so that the XP-computer can see/play the m2ts-files? Thank you.
