I am having a few problems with this but I think that it may be because some of the codecs have been changed/updated. I am using the newest KLMC1.51 and installed *all* options. Of codec lists that tommy posted, I don't get these files loaded: 3ivxDSMediaSplitter.ax ac3filter.cpl CLVSD.ax CoreAAC.ax CoreFLACDecoder.ax DirectVobSub.cpl ir50_lcs.dll MatroskaSplitter.ax mpeg2dmx.ax QT: qtmlClient.dll Although I did get a 3ivxDSmux.ax...could that be a new/replacement version for 3ivxDSMediaSplitter.ax? Real gets a bit weirder. I can get some of the files listed by tommy, but others seem to be new versions i.e., I get drv1.dll and drv2.dll instead of the "3260" series in tommy's list. I do, however, get some of the 3260 series: atrc3260.dll cook3260.dll Are my files all screwed up or does the thread need to be updated? Should I scour the net for the files? That would likely leave me with various mis-matched versions that may cause problems.
