PS3 Mediatomb Debian configuration - cont.

I recently made some improvements to my mediatomb setup, so here's my config file.
It now does some server-side transcoding for stuff the PS3 doesn't have native support for like Vorbis audio, video codecs and iso images.
It's not perfect yet, but it works for most of the stuff I've got.
The mediatomb xml is pasted first, then the support scripts which handle the video transcoding, just don't forget to chmod +x them (they can be used standalone as well btw).

About gallops and down picking

I've got some serious problems with alternate picking.
From when I first picked up a guitar down picking felt much more natural than alternate picking but now I'm starting to realize I've made a serious mistake ignoring it.
I've always wanted being able to play kick ass down picked riff like that MoP riff.
So I practiced and practiced and built up speed until it sounded pretty good.
Meanwhile I practiced galloping as well but somewhere along the way it went wrong and now I'm re-learning to gallop the 'proper' way.
A couple days ago I realized why this happened.

Let's take this riff from MoP as an exmaple:

A |-----2-----3-----4-----3-----2-2-- [...]
E |-0-1---0-1---0-1---0-1---0-1------ [...]
    D D D D D D D D D D D D D D D D

This is played at 218 bpm, so it's pretty fucking fast.
Down picking obviously implies performing a down stroke, then bringing the pick back up without hitting the string and down pick again and doing this really really fast.
Now let's take this basic gallop:

E |-0--0-0-0--0-0-0--0-0-0--0-0-0-- ...
    D  D U D  D U D  D U D  D U D

And this is where my problem starts...
I'm so used at performing the D-D movement, I'm now having the greatest problems performing a basic DUD movement.
Instead I noticed I perform a gallop like this:

E |-0--0-0-0--0-0-0--0-0-0--0-0-0--
    D  U D U  U D U  U D U  U D U

Somewhere along the way my brain decided to perform a gallop, which is a form of alternate picking of course, starting with an 'up' movement to, I guess, differentiate between the regular down stroke and an alternate pick.
When doing faster alternate picked stuff I caught myself starting with an 'up' movement as well, losing speed, needlessly creating extra hand movement so losing efficiency while doing so.
Detecting and realizing why one makes mistakes is the first step, right.
So now I've got to unlearn starting an alternate series with an up stroke by default and that's easier said than done.
