I'll move the SFV links to the first post. As far as how long term those links are, it beats me. I'll try to maintain them, but again the originals will continue to float around on the DVD's. So someone will always have them somewhere.
Way way down the line, I'm sure it won't matter, I fully expect my discs to be obsolete in under a year (if they survive that long). So relax. It's not the be all end all of the OT on the line.
