The author is a dumbass. I can't sugarcoat that.
I like how his image of Audacity shows the audio clipped and distorted. That's what happens when you use a POS like an Elgato to capture.
eBay and Craigslist have about an 85% fail rate with VCRs, with the items being damaged or simply in poor shape. Most sellers either lie, have no idea how to judge the condition (being recyclers and storage/estate buyers/resellers), or use some horrible packaging that the fine-when-auctioned/sold deck arrives broken. It's pure gambling.
The worst aspect is when newbies don't (at first) realize they've bought junk.
This has also led to the myth that "VHS was bad", when in fact a good VHS conversion can look as good as what you see on 4x3 aspect digital cable channels like Buzzr, RFDTV and Encore Westerns.
This is why non-video "tech writers" should stick to non-video topics.
Luckily my vet is just a few miles away.
