However when attempting to view a DVD at full screen, the display is a
bit "jumpy" as if the video hardware is not fast enough.
It's pretty hard to believe that the video hardware is the
problem. I've played back DVDs on laptop ATI chipsets a decade
older than yours and it worked fine. I've currently got a two
year old ATI laptop chipset (X300?), and it has no trouble
playing DVDs using either the Radeon or the fglrx drive.
My guess is the optical drive doesn't have DMA enabled.
DMA is enabled. If it were not, I would also expect to see the
choppiness no matter what the video size.
tagalong conf.d # hdparm /dev/hdb
/dev/hdb:
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
You may want to check to make sure the XV video overlay support
is enabled, but even without it, playing back SD video purely
in software shouldn't be a problem on anything with a CPU
faster than 500MHz.
How can I verify XV video overlay support? I'm sure my CPU is capable
as its an AMD Turion dual core running at 1.6ghz.
Thanks,
Drew
