Toshiba 8XDVD drive will not get DMA turned on on Secondary IDE channel.

[Mark V]

Hi all,
I am having a problem playing DVDs on my PC. DVD playback is somewhat choppy
and could be possibly attributed for winXP inability to turn UDMA/DMA on the
secondary IDE channel (DVD drive).

I have my bios set to auto on the secondary channel which sets the PIO mode
to 4 and UDMA mode to 2. I have winXP device settings for the IDE channel
to 'DMA if available' but it consistently sets to PIO. I had the DVD
connected with 40 pin cable, which i changed to 80 pin with no effect.

I am using PowerDVD 3.0 as the codec/playback application.

PC specs
Athlon 1900+
Asus A7N266-C motherboard 1.003 bios (NForce1 chipset)
512 MB ram
80 GB Maxtor 7200RPM drive
SB audigi
GF3 TI200
Toshiba 8XDVD drive

any help will be much appreciated.

Thank you.

Mark

I forgot to add:
Running Win XP pro SP1, all critical patches installed.

Saw someone else had a problem as well:

Finally, last night, I discovered (and I don't know why I
didn't look there first) that DMA mode for the DVD drive
was turned off and set to PIO! I never modified this at
all. The setting for the DVD ROM was set to Use DMA (if
available). I uninstalled the DVD drive and had XP
reinstall it, but it stayed at PIO mode.

The only way I could get this to fix itself was to
uninstall the secondary IDE device and have XP reinstall
it. That put my DVD ROM back to DMA mode and fixed the
choppy playback.

should I just unistall it from the device manager and reboot?

Thanks

Mark
