In the software business, there is ALWAYS a new driver!
MediaVision distributes CD-ROM drivers for their cards, and their tech support
has information on problems and fixes. Your best bet is to contact their tech
support line and see if they can help with your problem.
DON'T ever fall into the trap of "its always good to have the newest driver
anyway". That is NOT the case. If what you have is working, don't try to fix
it!
In your case, better discuss your problem with tech support at MV before
jumping the gun.
