Don't know if this will help others.. but.. My system now working and I figured out what was wrong using the Honestech installation. I noticed when I run thatm the v7, VHS2DVD application with the NW06 Vidbox, in the settings at the bottom, there is an entry for the video grabber, as above but, underneath, greyed out, is a 'Line In' entry, unused I guess, NO reference to using the NW06 Vidbox USB as the sound source. And that system has worked consistently, So, this morning in the 'Sources' option for the Vidbox, I unchecked 'Use Custom Audio Device', the NW06 Vidbox, was the entry, and the one I have been using all along, and instead used 'Output Desktop Audio(Directsound)' though the 'Wave out' also works as well.. And bosh, it all worked straight away..
I had assumed there would be some sort of entry for using the USB Vidbox input to the PC as a direct sound source, but can't see how this can be done.. In Sound Control PAnel, I have both my 'Mic Inputs' greyed out on the 'Recordings Tab' ?? Any suggestions about _that_ would be welcome..
Cheers
