VCD (DAT) files won't play all of a sudden : LUSENET : Video CD : One Thread

I installed an HP Cd Writer and all of a sudden the media player wont play VCD (*.DAT) files anymore. I've tried reinstalling the latest version of media player from the microsoft site, reinstalling my video drivers, (Canopus Pure 3d) and direct x (ver 7A) to no avail. I get a format unsupported message. This also happens when I use other players (e.g. Jet Audio).

This is what I did. Don't know is the HP CD-Writer will work afterwards though...

This is a very common problem which has been answered several times in this forum. You are missing SCSI1hlp.vxd in your windows\system\iosubsys directory. This file is necessary for your IDE CDROM to read, transer to the HD, and play VCDs. It somehow makes the IDE act like a SCSI. This is an integral file in adaptec VCR software. This is the file that makes NERO or WINONCD not compatable with EZCD creator. Your need to remove this file for NERO to work and NERO will remove it on installation. Most likely you redid your hard drive (format and reinstall) or just added new CDR burner software. This file is in one of the CAB files in the W95 or W98 install disks. Just expand it and put in the above subdirectory, and it will work. If you want to use NERO with Adaptec CDR software, then I would suggest that you write a BAT file to rename the file so that you can use NERO and then another BAT file to restore the file so that you can play your VCD or use EZCD creator (I do not know if you need to reboot after renaming the file since I never have used NERO). I always keep a copy of this file in another subdirectory just in case it gets accidently removed so that I do not have to search through windows install disk to again. Without this file a MMsystem error usually results when using a VCD player.
