Justin,
We are running 2.4.20-6, RH 9 distribution. (I set hda=ide-scsi). I had a
problem that may be related. My DVDR/RW will hang the system in the default
ultra DMA mode.
If I set the DMA jumper, this makes it some other version of dma (Multiword DMA)
which is supported by the kernel and it doesn't hang for reads.
However, I still haven't figured out how to make it write with cdrecord ProDVD.
