does it in the log say Stopping FFmpeg (or similar) every time you play a new file?

is this complete log or did you filter something out? It should try to kill the Windows processes before starting a new FFmpeg. The failures below look like failed FFmpeg commands, not failures to kill them.

i only removed logging lines from plugin. there was no errors when serviio tried to kill process like this

2012-11-20 20:31:26,625 DEBUG [org.serviio.external.ProcessExecutor] Stopping external process: Thread[Thread-853,5,ServioThreads]

was 853 Windows PID? if so then as you might see from screenshot above there was no such PID in Task Manager. did serviio use correct PID to kill the process?

[zip]

It should say:

Killing the Windows process: <pid>
