As I got a mention as having posted, because I notified FE about a Spammer on the Thread, I feel slightly obliged to see if I can help Elspeth.

Elspeth: I think the reason that you have had no response is that I don't think anyone knows of a Laptop that could run two different films at the same time.

Although I believe that a High-end Processor might, repeat might, be able to run two films simultaneously, I believe that two separate Graphics Cards would be required.

I doubt that there are any, normally available, Lappies available with such a configuration.

You might have to build your own. In which case a Lappy would be out of the question - No space for two cards.
