I'm using a Cameo Grabster unit to transfer old TV progs from VHS tapes to my hard drive. I've tried VDub and Ulead Video Studio capture software. While the capture is in progress, the audio sounds fine, but on opening the file on my hard drive, I get bad audio crackle. The crackle is not always present. This is guesswork on my part, but it seems TV channels with less sophistcated audio output produce none or very little crackle. Channel 700 will produce a better result than the major network channels, for example. Of the various audio settings I've tried for the capture, selecting mono rather than stereo is the only method of reducing (not stopping) the crackle.
Thanks in advance.
