Hi Gene, Usually I reply to tvtime email a bit quicker, but I have been away on holidays. There have been a few points of misinformation. First of all, Marius and hermann are incorrect, recent versions of tvtime use the left/right for volume, while in the past it was for fine-tuning. Hence there is some confusion. Second of all, tvtime's volume control only affects the volume of your mixer, it does not talk to the capture card (nor does it need to). If the microphone input controls your volume, you may have plugged your capture card into your microphone input and not your line input of your soundcard. Check that out first! By default, tvtime controls the 'line in' input on your mixer, check if this is correct. If you're still having trouble, please let me know. > I note that it puts a fairly heavy hit on the cpu, around 35-40%, is > there some option to turn on dma or something to alleviate that? There are many possible causes for high CPU. For one, tvtime is designed for full-screen high quality TV viewing, so using CPU to process the video is expected. There are options to change the processing which will make that amount go up or down. That all said, there are many, many possible kernel misconfigurations or video card driver misconfigurations that can lead to bad performance and frame drops, so if you're having trouble, let me know and I can provide more assistance in debugging it. -Billy
