some general MPC settings questions

[THX-UltraII]

Hi guys (and especially the makers of MPC HC, keep up the good work! :thanks, I m using the MPC HC edition for some time now and have to say that I am very pleased with it. Especially because of the Anti-tearing option! It resolved all of my issues I had before.

Still I have some questions about some general options that can be selected in the MPC HC edition. So I hope you guys here can clarify them so I know what they do/what they are for.

In the Options menu of MPC there are the following things I would like to know what they are for. In the Output menu:
- Surface: regular, 2D and 3D. Best to pick?
- Resizer: Nearest Neighbor, Bilinear, Bilinear (PS 2.0), Bicubic A=-0.60 (PS 2.0), Bicubic A=-0.75 (PS 2.0), Bicubic A=-1.00 (PS 2.0)
- YUV mixing: check or uncheck?+what is it for?
- Lock back-buffer: check or uncheck?+what is it for?

Then there is the Audio Switcher
- Enable build-in audio switcher: check or uncheck?+what is it for?

Thanks for all help and sorry for my bad English.
