Go to http://www.codecpackguide.com/ and install the K-Lite Mega Codec Pack. Then try again. If it still doesn’t work post here what GSpot (included in the K-Lite Mega Codec Pack) sais about the file.
Have recently downloaded a file that requires an audio codec that is not on my comp. I can’t work out which it is either. It isn’t AC3, this much I know for sure. the file has DSR.XviD-ORENJi in it’s file name. Any thoughts?
