Problems with Capture Frame -> "What you see"

[Id]

Yeah that's right
I got a PixelView GeForce 2 MX400 64 MB on WinXP (if that has anything to do with) and the program runs fine, but...
When I try to capture a frame (doesn't matter if it's a DivX AVI or MPEG), if I use the option "Capture frame -> original size" it works fine and captures the original size...
Now when I use "Capture frame -> What you see", instead of capturing the video's current size (Fullscreen for example, I even tried dragging the video's window), it captures the original size instead.
The only time it worked and that I could get a fullscreen frame captured was when I opened a video and BSplayer reported a sort of Overlay error, but the video would run just fine and so did the "Capture frame -> What you see", but it only happened once.
How can I get that option to work correctly?

Thanks for the help

Now I'm getting the following message whenever I try to open a DivX movie:
"BSPlayer v0.85.488, Unhandled exception at EIP: 1D1C4E86

Oh well.. can anyone help?

You have a conflict with the Morgan Switch. It's a filter that enable the selection of audio stream in Windows Media Player. BSPlayer doesn't need it, and used to conflict with old versions.

2 solutions:
- Remove or just unregister the Morgan Switch 'MMSwitch.ax' that should be located in your %windir%\system directory, using:
REGSVR32.EXE /u "MMSwitch.ax"

- Upgrade MMSwith to latest version.
For testing purpose I've just reactivated mine which is in V0.96B. It works just fine in windows mplayer2, and don't conflict when running BSPlayer.
