do u have the proper codecs installed cause i have it and there is no problems with it install the K-Lite Codec 1.6 from http://home.hccnet.nl/h.edskes/mirror.htm and then try and watch it
This is the ring (xvid) ye?? If so you need 2 things. You need the xvid codec and an ac3 filter. xvid codec - http://www.afterdawn.com/software/video_software/codecs_and_filters/xvid.cfm ac3 filter - http://www.afterdawn.com/software/video_software/codecs_and_filters/ac3filter.cfm
I dont really bother with codec packs, especially that stupid nimo pack that throws tonnes of unneeded codecs all over your computer so they can mess up everything, lol however if the makers of k-lite packed this then maybe it can be trusted
