No Picture or sound for recordings

[Cheenis]

Through using this forum I've managed to get picture for live TV, but the recordings I have made give me a black screen, no sound, but it does give me the details of the programme at the bottom. I'm guessing it is a codec issue, but I can't seem to get it to work. No doubt I am missing the obvious!

I've just installed on a Win7 64bit machine. I've put in the latest version and the patch in preparation for XBMC 12 (Frodo). The only things I have changed are the folder locations for live TV buffer and recordings and I have changed the MPEG2 Video decoder to MS DTV-DVD video decoder. Everything else is fresh out of the box build wise.

Any thoughts?

All help very much appreciated!
