[mythtv-users] DVD playback problems

[Piers Kittel]

Hello all,

Am trying to fix a few fairly major problems I've gained since upgrading 
to 0.20 from 0.19 where I haven't had those problems before.  Am going 
to try one by one...

Firstly.  On one of my Linux frontends (called Hinata) running Debian 
Sarge, I want to watch DVDs on it.  When I was using 0.19, I set up the 
DVD module to start mplayer with the relevant commands to make English 
subtitles display and point to the DVD device to /misc/cd.  That worked 
perfectly fine, until I upgraded to 0.20 where pressing return the menu 
just vanishes for a second or two then returns.  I get the following 
error message:

If I manually run "mplayer dvd://1 --dvd-device /misc/cd" it works 
perfectly fine.  So I wanted to sanity check what command the DVD module 
passes on to mplayer, but when entering set up, mythfrontend crashes and 
there's no obvious error message I could see.  The log file ends above 
as soon as mythfrontend crashes.  The following is mplayer's output when 
running the above command.

Any ideas of what I'm doing wrong here and how can I fix the problem I'm 
having please?

Thanks very much for your help in advance!
