hey,
im running openelec on my rpi with vdr. it runs good so far but every x minutes the video/sound stutter and the process mmcqd/0 use much cpu for like 5 seconds. this happens every x minutes. is my sd card to bad or what happens here? Sad

i have the sd card who comes with the pi, so i know nothing about it. maybe someone can help me Smile

edit: wow it takes over 10 minute after reboot, before this process stops using much cpu ... -.-

try to open another ssh connection to your raspberry and there type

Code:
tail -f .xbmc/temp/xbmc.log

and try to see what's happening when the mmcqd starts acting up.
my guess is the vdr refreshes the epg, at least for me that's what vnsi add-on does every x minutes.
other guess would be that somehow the network buffer eats up all ram and that triggers writes on the sd card.
hope this helps

i rly dont know what happens. i tried the dvblink server yesterday and there i dont see a single time the "mmcqd/0" process and he runs fine, but i want to use vdr Sad

what causes so much data transfer on vdr?

ok. now i was able to test it while tv, but nothing special is shown in the log. the mmcqd/0 process use the whole time cpu while tv and i have sometimes small and bigger "lags". this didnt happen on dvblink server Sad

top while live tv:

Code:
PID  PPID USER     STAT   VSZ %VSZ CPU %CPU COMMAND

1027     1 root     R     487m130.7   0 59.5 /usr/lib/xbmc/xbmc.bin --standalone -fs --lircdev /var

6655  6650 root     S     140m 37.5   0 29.8 vdr.bin -g /tmp --no-kbd --log=3 --port=0 --config=/st

  698     2 root     SW       0  0.0   0  5.7 [mmcqd/0]

EDIT: i found out, that epg was the problem. i disabled epg while live tv and now it seems to work much smoother
