Freeze problem while capturing 720p from Xbox 360 with Blackmagic

[Jeru]

Hello everyone.
As the subject of the topic suggests I'm experiencing problems while capturing HD footage from a Xbox 360 console.

I'm Using Adobe Premiere Pro3 3.2 for the capture. The Capture card is Blackmagic Intensity Pro. I've installed the Blackmagic codecs for Win XP Intensity 2.0 for Windows XP x64bit. The Xbox 360 is hooked up via the component cable.
The premiere project settings are as follows:

General -
Editing Mode: Blackmagic Undompressed
Timebase 59.94
Frame Size 1280 x 720
Pixel aspect ratio: Square Pixels (1.0)
Fields: No Fields (Progressive scan)

Capture: Blackmagic Capture

Video Rendering
Maximum bit depth is turned off
File format: blackmagic uncompressed avi
compressor: blackmagic HD 8bit 4:2:2
Color Depth: millions of colors
Optimize stills is turned on

So...

When I start recording everything seems ok. But after a few minutes or even 20secs of play/record time the picture freezes for about 5-6 seconds and after it starts again the recording has stopped (I don't press the stop button or anything it does it by itself). The recorded video plays until the crash moment.

I've checked the performance from the windows task manager while recording and even during the freeze problem the cpu usage does not exceed 20-22% and the PF usage remains at about 900MB so I guess the hardware resource is enough.

Any help would be greatly appreciated.
Thanks in advance!

Well... I can't think of any more info which may help.

If you have multiple hard drives, are your hard drives in a RAID0 array?

Yep, I have two 500gb hard drive 7200rpm 16 000cache (or something like that... don't know exactly) in RAID0.

I noticed something else - when I restart the PC and then try to capture it usually takes a while before it crashes. Just now after a reboot I recorded 1min and 30 secs.

I don't know what that could mean, but I'm writing it because it may be a clue for someone.
