Hello
Just thought i would fill you in on my findings.
I have tried a setup using a Mac Pro, Dual Quad 3.0Ghz, 4GB RAM, with an ATI Radeon X1900XT, outputting the video at 1024x768 on DVI to a second display.
I have then setup two video drives,
1 - 150GB 15000rpm SCSI Drive
2 - 2x150GB 10000rpm SATA Drive, In Raid 1 (Mirrored)
I am using the latest release of Catalyst, and all the current updates from Apple.
All test conducted with DV footage, motion JPEG to follow
Results:
SCSI
DV at 720x576 - 5 Layers till frames dropped
DV at 1024x768 - 4 Layers till frames dropped
SATA
DV at 720x576 - 5 Layers till frames dropped
DV at 1024x768 - 4 Layers till frames dropped
This is with no processing and playing full screen, not that it matters as teh CPU never went above 20%.
Cheers
Gareth
gareth-
dv doesnt work at 1024x768 - you can create the movies but it doesnt work- all quicktime does is resize a 720x576 movie. DV is both fixed size and fixed bit rate.

did you install the latest version of the atto scsi drivers - the ones on any cd didnt work last time i tried?
http://www.attotech.com/software/drivers.html
its shown as version 4.1 on the UL5D driver page.
you will need to login and create an account - if you havent.
if you didnt you need to as the default driver has very poor performance.
Hi Richard
Yes i do have the latest drivers from atto installed, and just to add some more detail, the SCSi drive is a Fujitsu MAX3073NP, and the SATA drives are the Western Digital Raptors WD1500ADFD.
I can't believe i never new that about DV, doh, i am just about to encode the same video footage as Motion JPEG at 60% and see how they compare.
Cheers
