i have a problem with my DMK31 USB2 on ICCapture 2.1 : I use it for several months without any problem, but i changed my laptop today, and i have somes freezes on avi record, but this is obviously not a concern of HDD framerate.

I explain :

- With my old laptop (HP 6910P with 5400 rpm 80Go HDD, with Vista 32), all was ok, 30 frames/sec was recorded on the HDD at 1024x768 without loss of frames.

- With my new laptop (Dell Vostro V13 dual core with 2Go Ram, 7200 rpm 320Go HDD, and the same Vista), on 1024x768 screen always freezes when i record an Avi, it freezes about 5 sec per 10/15 sec recorded, image freezes and HDD record stops. It freezes on 30 fps, 15 fps, 7.5 even 3.5 fps !!! On the avi, nothing is recorded when freeze.

- If i use ROI mode, i crop the screen only a bit, i/e 1020x764, so there is no freeze and the Avi recorded all the frames (900 frames on 30 sec and 30 fps).

Then I tested the DMK and ICCapture on my workstation, and there is no problem to record at 1024x768.

On the Dell Vostro i tested with the battery cell or the external power, problem is the same. On USB2 port, there is only the DMK.

DMK has no problem, ICcapture has no problem, i think the problem is somewhere on the Dell Vostro but where ? Vista is exactly the same as on the HP 6910P.

HDD problem ? I don't think so
Memory problem ? Processor problem ? Screen or graphic card problem ? Graphic configuration ?

Why when i use ROI and few pixel crop, all remain ok ?
