DVD player for old laptop

[Fraughton]

I just got my hands on an old toshiba 750dvd and I'm wondering if there are any dvd players capable of running on such an old system. The computer is a pentium 233MHz, 128MB RAM, 5GB HDD, Win98se and of course it has a dvd-rom installed. I've got it updated to windows media player 9, but of course it doesn't have a dvd decoder. I've looked up the minimum specs of powerdvd and it seems to require a 350Mhz processor for version 4 which I have. What programs were used back then to play DVD's on these old systems, if any?
And before anyone asks me why I want to play DVD's on such an old system, I just want to see exactly how much such a system is capable of. I don't plan on making this my media centre or anything.

Those old systems used a hardware DVD decoder card - and usually an old Cinemaster software player. You have a chance of playing a DVD with what you have if you put a video card with full DVD hardware assist in - or the machine has a hardware card in it already.

Ok. I found and installed the toshiba decoder driver for win98. Now I am able to play dvd's using the win98 dvd player, but there is only audio. Any idea what I may be missing to get video to work?
I looked up the cinemaster software but all I can find is their winxp version which requires a 400MHz processor.

Problem. I just enabled DMA on the DVD-rom drive and I now cannot even boot into windows. I tried to disable the setting in safe mode but the option doesn't seem to exist. I take it that DMA isn't supported by this drive. Any idea how to fix this without re-installing windows?

Boot to a command prompt, scanreg/restore - use yesterday's registry backup.
