I have installed the software on my brother's computer and it works but this is not a satisfactory solution because I am unable to use his computer on a regular basis. (basically he is allergic to noise - see hyperacusis). I have installed the software on both my home PC (details supplied above) and my laptop. I have now used four separate VCR's all with exactly the same result on both my pc and laptop - ie no signal but a black and white preview and sound in S video, nothing in composite. This now includes using the same leads, disc and video player that I used successfully on my brother's PC. However for whatever reason it will not work on either my PC or my laptop.
On my PC the leads provide a perfect image from the DVD player so it's not them. The device and software work perfectly for camcorder capture but will not capture VHS. I have used four different VCR's all with the same result, including one that works successfully with the software on another computer. I can only see that it is the way that the software is interacting with my computer and laptop that is the issue yet I have clean installed it 5 times, including copying the disc to HDD and then installing with startup disabled in msconfig on my pc. I have tried to "pass through" the DVD player as a connection but have not been able to achieve this - the DVD player just connects and displays its start-up screen and won't allow the signal to pass through.
