Plextor PX-716A DVD burner and xine (details)

[Raymond Lillard (rlillard)]

My problem is similar to Scot's (Plextor) and may be related.

I have installed FC3 (+ all outstanding updates) on a Dell 
Latitude D810 laptop.  The everything works, but I am unable 
to get my CD/DVD drive to use DMA. My experience with 
"hdparm" is the same as Scott's as described previously.

Interestingly, I have a Dell Inspiron 8100, which is nearly 
four years old running a fully patched FC2 OS with no DMA 
issues.  It is running kernel 2.6.10-1.770_FC2 which makes 
me think the problem is related to the 82801FBM (AKA ICH6R) 
in the D810.

Thanks for listening,
Ray
