I've read the comments about tape piracy and I agree that people selling these tapes on eBay for massive profits should be reported. However, I think it's a shame that some people have stopped copying tapes for others just for the cost of the video and postage. I know that I have had "illegal" copies of other series like this in the past but it has never stopped me from buying the official release on VHS or DVD when it comes out. The quality is obviously going to be better and, in the case of DVDs, there will be extra features too.
Having just discovered this site recently I was hoping to be able to get a copy of some of the series, but unfortunately it looks like that is no longer going to be possible. It's a real shame, especially now that Challenge have stopped showing it.
Oh well, hopefully there will be a proper release some day!
