I've had this happen randomly at times, particularly with PDVD. I was never sure if it was a Windows issue or a PDVD one. What happens from time to time is I get the centre mapped to the Left Rear and I dunno what else gets messed up 'cause it's kind of hard to identify. There's no mistaking people shouting at you from the left rear all of a sudden though, LOL. It usually starts when watching a BD and hitting pause (or ffw/rwd) at any point in the movie. Once it resumes after whatever function, it's channel mixup city.
It get fixed with a reboot most of the time. Then it goes away for a long time, randomly pops up again sometimes. Have no idea what causes it though.
If you have a modern AVR then you can avoid this by simply limiting multi-channel output to bitstreamed formats (TrueHD, DTS-HD). Couple formats you probably won't be able to do that with however, are AAC-multi and WMA-multi, which you'll have to use multi-PCM for. Personally my receiver is not new enough for bitstreamed HD formats so I'm stuck using multi-PCM.
So, if you can bitstream more stuff I'd say do that. Otherwise, rebooting should solve it, no? Again I have no idea why this actually happens but I have had it happen as well--you're definitely not alone.
