Problems with VLAB MOTION BPPC SCSI HD ZIV board

[amipuzas]

Hello, i'm doing a program to make stop motion with my vlab motion videocard, it's controlled via infra red or joystick, work fine, but i have a problem here, i test with 2 different SCSI hd (1-SCSI 2 2-Ultra Wide SCSI) and i'm not able to playback never anything with the movieshop software, ever i have transfer problems, and stop of play in 10-12 frames aprox. i test all the buffer options, with no luck, only can use 1.2 mb/s using dinamic cache from phase5, but is not a solution. Anyone with the same config and with this card running fine? (i'm expecting 2mb/s with scsi almost). Thx

yes underrun overrun and fifo related things
my program works of course but i'm improving it

15 mb/s sounds really cool but is not possible

i test with another scsi cable, another hard disk and i have the terminator jumper in my hard disk also (it's my only scsi device plugged in the blizzard ppc)
i have also a power flyer ziv i have transfers with movieshop around 1.3 mb/s more=problems and eat all my cpu.
