If this is the wrong forum, I apologize. I work with surveillance video on occasion and one thing I have run into are stores that are still using multiplexed VHS tapes. I usually have to bring my laptop to these places to capture the video as they will not play on a regular VHS player. I've been on Ebay and there are a number of multiplexer devices on there. My question is, do all multiplexer devices work the same? Or will the recorded VHS tape be bound to that same model multiplex device? I don't want to waste my money if the one I purchase will only work on 10% of multiplexed VHS tapes.
