I tried 30, 25, 20, 15 fps -- the same result: when MVK-files reeaces 2 GB, guvcview hangs up...

I doubt, that AVI is better... :-)

Yes. 30, 25, 20, 15 fps... 960, 800, 640 pixels... [On a Core i5 processor.]

Yes, tried MPEG2, H264... The same... 2 GB... (on any FS: ntfs, ext3...)

I will try without audio...
