Hi,
I'm trying to get my Hauppauge WinTV PVR-250 to work, but I only get loads of
"DMA TIMEOUT 00000003 0" messages and accordingly the LifeTV and recordings are
more than choppy.
I've followed the suggestions on this mailing list (like setting DMA in BIOS
and hdparm, changing PCI latencies and buffers, using different kernel and ivtv
versions), but nothing helps. Right now I'm on 2.6.24 with ivtv version 1.1.0.
My server has a Compact Flash card as hda, which apparently doesn't support
DMA. But all ivtv streams go to/via a "real" hard disk (hdc or hdd) on the
second IDE controller. If I understand dmesg correctly, they're running in DMA
mode, but PIO is also mentioned.
Could there be an issue?
Any help is appreciated!
Cheers,
Steve
