I have used coreavc codec to decode bbc hd h.264 with the directshow
patch by alan nisota, it worked fairly well but there were some slight
audio sync issues.

System is core 2 duo 2.4ghz with nvidia 7600GT 256mb, overclocked to
3.0ghz. 2gb ram.

Unfortunately I lost my mythtv "registry" file which contained my name
and serial number, and when i tried to reinstall the codec on my
windows workstation at work it said that the serial number had already
been used, I emailed coreavc about it and got no response.

Something (I seriously suspect the coreavc installer) blanked the
product key/code on my windows system, so the coreavc serial number
that was already in the registry was no longer valid as my product
key/code was no longer the same and it is used in the key validation.

The codec is no longer available for online purchase (i would buy it
again if it was!), the codecodec website says that sales will be "back
soon", its been like that for 3+ months.

</rant>

I dont think its possible to decode h.264 mbaff in real time with any
free codec :(

But transcoded to xvid, bbc planet earth is absolutely breathtaking!
