What's interesting is that video tapes deteriorate over time. The binders that hold the magnetic oxide to the plastic tape become undone and actually makes the tape sticky. If you play it in your video cassette recorder/player, it'll start squeaking, gum up the heads, and ruin the cassette player. It's called Sticky-Shed Syndrome. You can actually temporarily repair your tapes by baking them at low heat for 8 hours or so. Anyway, I bring this up because I'm sure CGC will just grade the packaging and doesn't check if the cassette is even playable. I would be impossible to check playability because if the tape is bad, it'll mess up the player and they'd have to repair it over and over again.
