I somewhat recently got windows media center and now I'm using the xbox360 as an extender to play videos off of my computer. .wmv files work great but I have .avi files that I'm trying to convert to .wmv files so that the media center will regonize it but im having trouble figuring out how to do that. Right now I'm using windows media encoder x64 bit edition with the k-lite codec installed but I keep getting errors about missing codecs and therefore I can't convert the file. I also tried using transcode 360 but I get an "unable to queue files for transcoding" error or something like that. I've spent hours reading guides on both issues but I've come to no conclusion. I even tried using windows movie maker but it only plays sound and the video screen is blank. Its reading as an audio file only. I'm not really familar with all this codec stuff but if anyone who has gotten this to work and can help me out it would really be appricated.
