Lost TV comedy 21

This one from 1997 by writer Roy Clarke who also wrote Last of the Summer Wine, Keeping Up Appearances, Open/Still Open All Hours, etc. and who will be reaching the age of 90 in a few months. Starring James Fleet and Jan Francis, who both did great jobs in this, with Anne Reid, Alistair McGowan, Rebecca Raybone, Julia Deakin, Brigit Forsyth and so on.... Joan Sims made an appearance, one of the last few things she did. I'll put links for two formats. I can't tell if one is better quality than the other. They look about the same to me. The .avi files are off-air recordings while the others are not.
