Yes Gary i read of your bad luck with the newsletters ! i bet the tape is in the case of not returned .
Best case i recall you could get a tape to the uk in a week but to here it tended to take bit under 2 weeks ,these days the post must be dreadful for any thing the size of a video tape.
But you could use a mini sd card these days an improvement in postage costs, the thing could be posted in a letter, so things even out a little .
Any case i hope the video still exists !
