Yes i found the patch mail and noticed it hadnt been applied yet (if
it is going to be). Thanks for the heads up on the h.264 codec. Will
keep an eye on it, may well try out the pay drivers as they arent much
but i still disagree with paying for software.

Think I may be getting confused about the cards, still trying to find
any straight info as to whether a dvb-t card here in the uk will be
sufficient to capture the stream. I am beginning to believe it is
though not sure.

I think the bbc starts their trial in the middle of may so will try
some things out more then.
