Make sure to check your tapes for mold before running them because that will mess up your VCR heads pretty quickly if you didn't.

It's fairly easy to clean the mold off depending on how bad it is. I also digitized all my family's old home movies last year and I had a "cleaner" VCR that I'd put the moldy tapes in. Fast forward all the way through, rewind all the way back, repeat a couple times until it's all cleared out, then clean the heads with some rubbing alcohol and repeat. Wear a mask while doing so. I had one that looked awful, like the tape was completely white so I figured it was beyond repair but it ended up working and the picture quality was great.
So if you've got moldy tapes, I'd recommend buying a second VCR for that part of the process.
