I've tried to record from google video and to use uTorrent with 5 downloads and I had no any problem with WM Recorder.

Then I tried to record 2 videos from google video, play one of them and use 5 downloads in uTorrent. Choky video in the embedded player stopped on a third minute, but WM Recorder downloaded 100% of both videos.

Do you download videos from vp.video.google.com or video.google.com ?
