I'll update this thread with more details, if there's interest.
I've not tested it since 2012, but I have the old Dazzle/Pinnacle 500 USB capture card. I've seen a lot of discussion amongst other forum members here lately. Perhaps somebody wants to try one?
Comes in original cube box, all paperwork, software (that you shouldn't use anyway), etc.
It was used for a single personal project by a friend, which he had me redo (his fault, not card), and my payment was this card, his JVC VCR, and his TBC. He tried to DIY, and it was a fiasco.
This card was $99.95 new in Best Buy in the 2000s.
Price is $50.
