Unless the SCSI controller is "reserving" completely the bus for long times unneedlessly? Or maybe it uses all PCI bandwidth for a short time, but for too long so that BTTV loses data? Also, why this happens only when _writing_ to SCSI, not at all when _reading_ from it? What comes to RAM, I have 1 GB ECC. (This is Dell Precision 420 Workstation). I'm using kernel 2.4.21 (forgot to mention). Also, I tried bttv options "triton1=1 vsfx=1", no change at all.
