Yes thats how intelligent random works. You should not think of it as
all songs in the playlist. Instead think of it as if I play 100 tracks
from my playlist, 15 times my favorite track will be played, 10 times
the second best etc. It is of course a lot more advanced than this, but
thats the basic idea. There is a new version of imms out, which is what
is used for intelligent random, I'll look into upgrading it.

Ok will fix.

The number of folders should have no effect on the speed.

Yes fbdev is really slow because it has to do resizing in software.

It really shouldn't matter. You can benchmark it but I don't think it
will make a difference.

Probably couldn't hurt, but I don't think this is the problem as you use
the same version on both machines. Could you post numbers for the fast
one in sdl and fb? I don't think that the 21ms for the slow one should
be a problem. That should be enough to render something like 45
frames/sec.

Yes its on the TODO. Will see if I can get it into 1.0.1.

Hehe, nice to see that someone else can use the code in mmsv2 :)

This is a very nice link. I have committed a first draft version of
dvbout to mmsv2--mainline--1.0.1--patch3. Please test and report back.
Not even sure it compiles :)
