It took me a while to get VCD's working in XP Pro. The WMP (both versions) were not all that keen on playing these files. I kept getting "unsupported format" errors and such. This is all a thing of the past now, ever since I installed WinDVD. So the playback is no longer the problem. The copying on the other hand, is. When I try to copy a .dat-file, I get the error that this is an "invalid MS-DOS function". I also read that this can be avoided by placing the file scsi1hlp.vxd in the system\iosubsys directory. The problem is that this directory doesn't seem to exist in XP. Also I read somewhere that W2K and XP don't use virtual device drivers. Can anybody clarify this and/or give a solution to this problem? Thanx in advance.
