Windows Media Player 12, Windows 7 does not play AVCHD (.mts) video in embedded mode, but does in normal mode

Question

I've run into a problem with WMP 12 on Windows 7 involved in playback of AVCHD files.  When run in 'normal' mode from Windows Explorer, WMP opens the video file and plays it back beautifully.  However, I'm building an application with
WMP embedded.  When running WMP from within the application (c#), the same AVCHD plays audio but no video.
I've seen this type of problem before with respect to audio playback of mp4 files in WMP from embedded-mode:  the MP4 license prohibited audio playback when run from embedded mode but played the audio fine when WMP was launched from explorer.
 I was able to solve this particular problem by using a 3rd party codec pack.
In this case, I've tried a number of packs K-Lite, etc., but to no avail.  My problem persists.  I suspect perhaps I've encountered a similar licensing-type issue with a SONY CODEC and the state in which WMP is playing back files but I
have not yet been able to track it down.
Any ideas?

Hello,
It seems that you are using the Windows Media Player control in a window form forum, 
as far as I know, the Windows Media Player control does not raise an exception when it encounters an error such as an invalid URL. Instead, it signals an event. Please try to set an event to try to catch the expcetion as described in the link below:
