Aley, I'd started to type a longer reply to this, but I just can't be bothered anymore. It's clear we have very different approaches to pretty much everything. I'm just not willing to make the same compromises as you when it comes to preserving media. If it doesn't work without modifying it, you need a better quality copy.
