Heres a SIMPLE program to force audio and subtitle streams to be auto selected with MOVIE ONLY rips created with tsmuxer.
If you are running it under Vista then you will need to run program as "Administrator", to do this, create a shortcut for the program, right click it, click properties, click advanced, tick the box marked run as administrator and then ok, and ok again. Now everytime you run the program using the shortcut, it will run as administrator
By the way, the program is a VB6 program, if you have not got VB6 runtime files on your system then there is a simple file you can get from microsoft site to install the run files you need for any VB6 program.
