Sorry for the confusion, i think that is the card that is recommended ny the mjpegtools guys as well. For firewire, some new boards have that onboard. I have bought a firewire extension card for this back then i got my dv camcorder.

For exact model i would search trough the mjpeg mailinglist archiv.

I have a Samsung 5400 120 Gig with 2MB cache here an plan to buy a second one in near future. 120 Gig = 50 hours dvb mpeg2, does not know how much you have to calculate for mjpeg and how fast the hd has to be. If you plan to make some video dvd i guess you can't get enough. scsi2 i think isn't worth the money here. For a definitly answer i would ask on mjpegtools mailinglist. Steffen
