The notebook is an Inspiron 9400. I think you're right that the problem 
is in kernel support for the chipset. lspci reports:

00:1f.2 IDE interface: Intel Corporation 82801GBM/GHM (ICH7 Family) 
Serial ATA Storage Controller IDE (rev 01)

but that may not be the same chip the optical drive is using. At some 
point I'm going to have to upgrade my kernel (currently 
2.6.19-1.2911.6.4.fc6) but I've put that off because I'd have to upgrade 
the ATI driver & the Broadcom wireless driver, both of which were a bit 
of a pain. I'll probably get Fedora 7 loaded & use that as the upgrade 
excuse, but the kernel driver may not be much better.

In the meantime, especially since my cache tests this morning, the 
method that seems best is to dump the VOB to the hard drive, as I had 
been doing, and enable the subtitles while playing that dumped file.

Thanks for your thoughts on this.
