Right now you can only record audio and video together. 
You have to set filters for both before recording.
Fixing it to allow audio OR video only recordings should not
be too difficult (and is on my list), but allowing audio and video from
different channels would be something different.

All this only applies to the filters of type PES_VIDEO and PES_VIDEO,
i.e. those which go to the MPEG2 decoder. That's because the recording
process of those is very different to that of the other filters.
You can of course set filters of type PES_OTHER independently of 
each other.
