1. Forget the VHS-C adapters.
Unless it's a powered unit (example: JVC CP7U), it's probably not any good, and will give you problems. Worse yet, many VCRs will "eat" VHS-C tapes -- even professional decks! Instead, you can simply repack VHS-C tapes into normal VHS tape shells. Yes, it takes a little bit of effort, but you also avoid risk associated with the 'C' format of VHS tapes.
