Previous & Next Chapter Shortcut don't work (1 Viewer)

[letoon]

Hello,

I'm a newbie with MediaPortal (previously, ,I was using Meedio). But I've got a simple, but big problem (for WAF).
Buttons previous and next chapter on my remote (imon inside) don't work. In fact, the problem does not seem to be from the remote control, but from MediaPortal. If I try default shortcuts during a movie playback (in fullscreen / VMR9 / on XP) nothing is done. F7 and F8 shortcuts don't work.

Any idea?

I found a reason. Could you confirm this?

In fact, my movies are in ISO files on my HD. And, I think that MediaPortal uses its movie-module to start playing them, and not the DVD module. How can I conclude this? By modifying codec settings, for example by adding FFDShow (with OSD/frame infos) on one of both, then swap this setting. According to this test, the movie module seems to be used for my ISO files.

If I well understood the situation, how can I change this? In other hand, I uses DaemonTool to open my ISO files.
Any ideas or comments?
