UPDATE : Don't use this, try kffmpegthumbnailer, it's way better and faster :)
This is a slightly hacked version of mplayerthumbs and intended for those who have a fetish for a "picture-perfect" desktop, whatever that means.
The thumbnails generated by mplayerthumbs look somewhat ugly, IMHO - that is, there is a thin blue(cyan ?!) strip, and only on the left side of the image!
So I decided to change the code a bit to generate thumbnails with better-looking stripes - delicious(I hope) black-white stripes on BOTH sides of the thumbnail.
Hope you like it.
PS: This might replace your existing mplayerthumbs.
PPS: This is actually really simple - I only added about 10 lines of code - most of the work was done by the author of mplayerthumbs :) (Excellent code, btw)
PPPS:Installation instructions are in the just check the README file.
PPPPS: There wont be a PPPPPS.
[patch] : Ok, the first version simply did not work on some people's computers, which was due to a conflict with the preview libraries of the original plugin and this. It is now fixed, it works.
