I've run into so many problems it's stupid. What's even worse is that I have been using a well put together guide by Assasin. And I seem to be hitting road blocks left and right. Using MakeMkv I ripped a blu ray to my M: drive, I then downloaded and installed the Lavsplitter codec following all directions properly. Then, I directed Windows Media Center to the location of my MKV file M:>Media>Video>HD Video. Windows Media Center refused to find the movie. I tred a ripped DVD in a similar location M:>Media>Video>SD Video, and then proceeded to again direct WMC to the file. Again it failed to do so. Googling the issue brought me to an old solution of using a registry entry to 'make' WMC find the file. It worked for a little while (hour or two) but when I rebooted it now again, no longer can find the files I am directing it to! To add to my woes, when WMC was able to play the ripped blu ray MKV (earlier) it had a 'skipping' issue where every now and then the movie would skip here and there. The ripped DVD on the other hand had no such issue. Troubleshooting the skipping issue, I went into Lav Video settings, and chose Nvidia for hardware acceleration. Still no dice, same skipping issue. What on Earth am I doing wrong ? This is a completely fresh Windows 7 64bit install, with all new hardware. please somebody help me.
