I'm trying to set up PowerDVD (in cinema mode) as an external player for use with XBMC. However, I have not been able to get the current version of PowerDVD (12.0.2118a.57) to play back a DVD folder from the command-line. I have been using the instructions in this post.

My DVDs are stored on X:\DVD\Films, so the VIDEO_TS.IFO for Excalibur could be found at X:\DVD\Films\Excalibur\VIDEO_TS\VIDEO_TS.IFO for example.

All three of the following launch PowerDVD in Cinema mode, but nothing further happens - the film does not play, nor is it selected.

PDVDLaunchPolicy.exe AUTOPLAY X:\DVD\Films\Excalibur /LaunchProgram PowerDVDCinema PDVDLaunchPolicy.exe AUTOPLAY X:\DVD\Films\Excalibur\VIDEO_TS /LaunchProgram PowerDVDCinema PDVDLaunchPolicy.exe AUTOPLAY X:\DVD\Films\Excalibur\VIDEO_TS\VIDEO_TS.IFO /LaunchProgram PowerDVDCinema
If I change PowerDVDCinema to PowerDVD in the above all three work - PowerDVD launches, loads the relevant DVD and displays the resume/restart prompt for that disc.

If I remove the /LaunchProgram switch then the behaviour is much the same, depending on which was the most-recently used PowerDVD mode (if I most recently used Classic mode, the classic player loads and works - if I most recently used Cinema mode, the cinema player appears but does nothing).

I'm pretty sure this was working in a previous version, but may have dreamt it - has anyone else got this to work, or is it a bug (or known limitation)?
