My pc is not the fastest and I prefer to record losslessly with minimal compression, and later convert, and this was a bit too much for my pc too. Or I shouldn't use h264 in this case?

(Of course audio didn't work. Could anyone tell me how to record the sounds too?)

If you just want to capture to a lossless intermediate format, you could try huffyuv/ffvhuff. Should be pretty fast.

(Alternatively you might also give Lagarith a try, which should compress a bit better and supports multi-threading)
