0-2% CPU usage while recording? Well that is pretty impressive... I always watch avirec with top when testing, I do not know gkrellm. I have an Athlon 850, I can record deinterlaced, in YUV2 colorspace (default), MP3 at 128kbit/s, size 480x360 with DivX ;-) Low Motion, XviD about the same. And I get the same values with avicap. I cannot believe that avicap does hardly use any CPU time... it may be lower because it cannot deinterlace and does not record MP3, but 0-2% is impossible.. Also notice that both avicap and avirec spawn several threads, only one of them really uses much CPU. Which options do you use for avirec and which for avicap? Mermgfurt, Oliver -- It's true!
