Problem trying to play a .dvr-ms file

[phoenix]

I just upgraded to version 1.37 Build 826 and was trying to play a .dvr-ms file recorded with Windows Media Center. I previously had version 1.32 build 820. In the older version, the recorded TV opened in the normal BS Player window where I could size the video to 16:9.

When I tried to open one of the files in 1.37, it opened in a window labeled ActiveMovie Window. I am unable to resize that window for aspect ratio.

As I can't get rid of it, I reverted back to 1.32.

I use a Windows XP SP2 computer that is less than 6 months old and I've never had this issue before.

I'd love to have 1.37 as it has a number of features that 1.32 doesn't have. Any help on how to get rid of ActiveMovie Window would be appreciated.
