and here's a top snapshot:

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
9324 mingo 20 0 300m 59m 17m R 96.4 6.8 21:00.55 kaffeine
9325 mingo 20 0 300m 59m 17m S 2.0 6.8 0:15.57 kaffeine
9327 mingo 20 0 300m 59m 17m S 2.0 6.8 0:20.10 kaffeine

so 9324 doing the mpeg decoding seems to be stuck somehow?
