If I try to turn on DMA, I just get WDMA2, which just doesn't cut it:
I think any DMA mode is fast enough to handle a DVD drive. There's just no

WDMA is not UDMA. Any UDMA variant would be enough. WDMA2 provides a
maximum of 16MiB/s, which will frequently lead to buffer underruns
viewing a DVD. UDMA2 provides a maximum of 33MiB/s, which IS plenty.
16MB/s is exactly what is needed for 12x DVD access. I think this is the usual
speed for a Notebook drive nowadays and it suffices for me.
# atacontrol mode acd0 udma5
current mode = WDMA2
Same as for me. I'm satisfied with the speed of the drive.
I'm rarely satisfied - I'm quite often not bothered enough to pursue :)
Well, if 12x speed is not enough for you, you have to use an external drive.
This is not a driver issue. It's just what your drive supports.
