regarding newclock4 build #0813b. How can I force using dvdplayer?

I have an ISO of a DVD (including menu etc.) that starts playing in 4:3 instead of 16:9. However, when I STOP (not PAUSE) and resume it, it plays in 16:9: I suppose dvdplayer is used at start and omxplayer when resumed. I have made a sample of the movie, but how can I force openelec to use dvdplayer to play it?

Bring up codec info ('o' key).
If the codec is like "omx-mpeg2" then you are using omxplayer.
If the codec is like "mmal-mpeg2" then you are using dvdplayer with hardware acceleration
If the codec is like "ff-mpeg2" then you are using dvdplayer with software decode.

If you go to settings/video/acceleration you can disable "auto" and either enable or disable "omxplayer" to force a specific player.

But, if you believe the behaviour is incorrect (with either player), then post the sample and I'll investigate it.

It seems that the problem is when going from the menu to play the movie. I have send a PM with a link to the file. Same behaviour with omxplayer 'on' or 'off'.

I do not have a keyboard attached to my raspberry pi, and the 'o'-key on the xbmc-remote-keyboard (iPad) don't do the trick.
