I am having problems (pre-)transcoding video files for my Panasonic TV. The main problem is multiple occurrences of FFMPEG.EXE that don't stop when I stop the server. I have also had the following issues:

[1]I open Mezzmo on my TV and it seems to want to transcode most my video files at once
[2]It creates a temporary folder today with a transcoded file and then creates a new temp file tomorrow and starts transcoding the same video again
[3]I added a wireless repeater and now I need new transcoded files
[4]I look at the pre-transcoded file for my videos - it is there in the morning but gone in the afternoon or when I want to view it.

I purchased Mezzmo but I can rarely get it to work properly. It is like a wild beast with many heads that keep replicating. I just want to control what videos I want to transcode now from my library. I guess I have to stop the transcoding process when I want to watch them on my TV. Any tips or hints would be helpful. "On the fly" transcoding is not possible even with my I7 processor and new Panasonic Plasma TV!
