Hi guys, bit of a weird problem. When I came back from holiday surround sound stopped working for certain things. I use SPDIF output and surround sound works fine for anything played on DVD, blu ray, or using the TV series plugin. But using Moving Pictures and I either get no sound (in the case of DTS) or a downmix to stereo for dolby tracks.

Anyone know an easy way to debug this? Its driving me nuts! thanks!
