Perplexing Plextor Problems

[ctcomedy]

Here's my dilemma . Please share if you have the same problems, or even better, a solution.

I have an AMD k7-600 (plenty of RAM almost 400) and 80 gig HD.
I have microstudio 2.315 and 2.4 upgrade (with KHPRO, VOGONE, and KEYRITE bundle)
I am using a Plextor PX-W1610TA, for burning. (atapi)
I had to uninstall ide board drivers to allow the DMA switched on , on the plextor.
It reads most of my CDG's well, and fast (good copies, strictly for archive of course) but certain CDG's only read intermittently.
I have some Party Pack CDG's which will sometimes read and then not, no matter what aspi , read speed,or other settings I change. certain other program cd's that read in my cdrom, will also not read in the plextor.
It seems once it glitches, and I get the series of 8 flashing lights.
It's just stuck, you almost have to reinstall microstudio to get it going again.
Is this the Plextor? the cdg's?? some settings I've missed??
Has anyone else had , or solved this recurring dilemma?
