don't forget about mplayer and media player classic, both very good players (mplayer even comes with an encoder, mencoder).
And they both play QT/RM and even flv. You might need the QT/RM Alternative codec though.
I'm pretty sure I've seen the structure of the setupfile somewhere, I don't know if it is for the current patch though.
Anyways, it shouldn't be that hard, as long as the setupfiles have the same structure (which I guess they have). If I get some free time on my hands (i.e. if I'm not lazy as usual) and nobody else will have done, I could do that
One of my cats did already see the LFS forum in a thread way back click for pic
Almost all of our cats were not planned to have, somehow we ended up with 5 of them.
