Choosing which DVD decoder to use

[hrlslcbr]

Someone here know how to choose the DVD decoder for playing files if there's more than one installed?. For example, I have PowerDVD 5 installed, and if I install Mainconcept encoder, it will install its own decoder, but I've read here that it produces problems for playing back files in some players, so what I want to do is to make the PowerDVD's decoder the default one to be used by any application. Is this possible? Thanks for your help.

If you right click on any video file and click 'open with'

you can select a program or browse for one and there is a checkbox to use that program as the default for that kind of file.

I was asking about choosing the decoder not the programme...
