Vista - Media Player has stopped playing .ts files

I've not long had Vista (Home Premium) and the windows media player that came with it used to play the .ts files that I'd exported from my digibox hard drive. Then - for apparently no reason - Media Player decided that it was no longer going to open the files, not even the ones that it had opened previously. It came up with the cood1199 error, but I don't understand why it's stopped playing them as it used to. It's infuriating. I don't want to have to download another program to play them when Media Player should - as it *did* - play them. Is there anything that I can do to get it to play what it used to play?

Have you tried a system restore back to when you know this worked or is this to far in the past? Have you tried to play the files with something like Realplayer. I know that you want to use WMP long term but this would confirm that it is a WMP issue.

Also found this link if it helps.
