Perhaps a short prayer to saints Crispin & Crispinian might help?
The other day, I experienced a sudden desire to watch Larry Olivier in the 1944 film version of Henry V, and Ken Branagh in the 1989 version of the same. So I ordered both through Amazon, with a bunch of other films from my wish list, and eagerly awaited their arrival. They were duly delivered, but I've had no luck viewing them so far -- as soon as the programme started, it cut out again, flashing either of two fairly incomprehensible messages on screen; one for Larry, telling me to update my drivers for my video card, and one for the others telling me the video card is knackered. Some deductive reasoning helped me to solve the problem pinpointed in the second message, but Larry's still not working. Woe.
One of these days, I really should get myself a proper dvd-player. After all, they're not even that expensive anymore.
