Angle matters more than vertical, 45 degrees holds best.

The "Worms in Space" fake problem is so real, I went through like four downloads that were just the normal cut with a different label slapped on. What finally worked for me was skipping the big public trackers and going straight to a private lost media Discord where people trade raw VHS rips instead of re-encodes. The trick is to ask for a timestamped screenshot of a scene that only exists in the pull, that weeds out the fakers in about two minutes. I also made a deal with a guy who had a capture card, he digitized his tape and I sent him a few tapes from my own stash in return. eBay sellers are mostly just burning the same bad rips onto DVD-Rs and calling them rare, so I stopped bothering with that route. Trade with collectors who actually own the physical tape, that is the only thing that has worked for me.
