Thank you both for your replies.
@Andrew Martin:- I accept the (implied) rebuke: you are of course quite right! The fact is that because I was dubious about the value I would be likely to get out of an outlay of around £140, lacking any positive reassurance my interest in acquiring the BM product waned pretty sharply and has remained dormant. I agree of course that it was always open to me (still is) to contact the manufacturer, but there's no real substitute for users' first-hand experience, which was/is what I was seeking to hear about.
@Xtreemtec
One issue i see coming is that the Shootview will not be able to track the VHS recorders propperly as i see nowhere mentioned that it has a TBC (Time Base Corrector) inside. And most VTR's the tracking is not that good.. Especially with older tapes..
I ought to mention that the VCR I'm using to capture from (a JVC HR-S8850EK) has JVC's "digipure" system which includes a line TBC and NR. May I ask you whether in the light of that you would nevertheless still anticipate those issues with the Shootview? The tapes I'm converting date mostly from the '80s and '90s and were recorded from broadcasts, many of them (I'm ashamed to admit) with 'LP' activated.
