In case anyone was wondering, I fixed the problem by buying a new motherboard. Seems there are other mentions around the net of PCI trouble with the VIA VT8233A chipset. I bought an ASUS P4B533 (intel 845E) and everything works fine now. ----- Original Message ----- From: "Neil Radisch" <nradisch@xxxxxxxxxxxxx> To: <video4linux-list@xxxxxxxxxx> Sent: Sunday, March 30, 2003 7:21 PM Subject: bttv and disk I/O trouble > This problem is v4l version 1, kernel 2.4.20 > bttv driver 0.7.105.
