I don't know why capturing as you're doing would be faster with MSP8. You're capturing in real-time, so the only difference might be the encoders used, to create the file. Rather than getting just little bits of information to work with here, Please go to the sticky Please Read this before posting
, or you can also view the Video Tour
which also mentions the information needed. I know that you're not getting audio, but you should with MPEG-2 audio.
Not being familiar with your Pinnacle device, and that your using composite cables to connect a part of it (to a PC card in your computer, or from a VCR or TV to the device or both), I still don't know why you would not be getting audio. Have you checked in your systems' Control Panel to see if the Line-In setting is muted? Right-click on the speaker icon in your windows task bar, select Adjust Volume Control
. First see if the volume control for Line-in is present, if so see if there is a check box beside Muted, or the control slider is all the way down. I've had strange things happen, where the slider was all the way down for various settings, even though I did not move it there.
