Some are recons, some may have occasional episodes missing (also missing from the BBC archives). The good news is all future episodes exist. If you see an episode you enjoy, please do consider buying it!
These are not a replacement for the original DVDs, so if they are on sale, I urge you to consider buying them if you enjoy it.
