First, my Alienware Alpha has always had problems with Tivo streaming. However, usually I can get a brief moment of flawless streaming from the Tivo after an nVidia driver reload, but now that doesn't help. The video stream has glitches with audio pops and what looks like timing errors with frames freezing and the like. I should note only this PC has problem, the stream works fine elsewhere. I am not sure how to troubleshoot this further. Thanks in advance for any insight.
