I have several .mkv files that I had previously converted to .mp4 using GotSent so I could watch them on my Xbox360 without having to go through the Media Center interface. I can get those to work for about 24 minutes on a TiVo Premier during a transfer then it just stops. If I try to transfer the same file through the Tivo GUI and wait until it finishes the blue light turns off after about 30 minutes, but my file does not show up. If I try to push it via the Desktop Plus interface it hangs and I have reboot my TiVo for it stop trying to transfer, long after the Desktop Plus server has been stopped. If I do the same thing for a Xvid based .avi I have no issues. I paid for Plus so I could to do this, and it is frustrating that it isn't working. I'm trying to eliminate my need to use my 360 as a streamer so it can be moved to another room. Also I am using a wireless "gaming adapter" via the ethernet port. This has worked fine for Netflix HD streaming so I'm not concerned about it. I guess what I am trying to ask is what is the best way to get my original .mkv files to play on TiVo via Desktop Plus?
