I have a XBMC on Raspberry Pi - Open Elec. Most videos play correctly but some, like DVD, play output like a volume meter.
Probably I need to install some kind of plugin?
Note: I found this, but the video is DVD (TS_VIDEO) not MPEG2 ...?
Install MPEG-2 and VC1 video codecs
In order to play MPEG-2 and VC1 video files, you will need to purchase codec licenses from the Raspberry Pi foundation.
Install the codecs by following these steps:
Purchase MPEG-2 and VC1 codec license keys
You will receive the license key from your email within 72 hours
In Raspbmc, go to Programs > Raspbmc Settings > System Configuration
Enter the license key from your email to MPEG-2 and/or VC1 codec under the Advanced system settings
Reboot the system
