I installed the new codec 1.7 full and then tried to play some avi files on my machine and would open up ok in any player (could see the time bar) but nothing would happen just a blank black screen with no sound. If moving the seek bar along still nothing.
Have checked the files using g-spot and have correct codec's for audio and video.
Then after checking some other posts relised there is another codec being tested version 2.0. Downloaded this (full) and installed and excatly same problem as before.
All mpg, wmv files work fine.
Even tried installing codec pack 1.6 to no avail.
NB: Also noticed in another post someone said the time bar when opening mpg files was shorted i had the same problem as well until i installed codec 1.7 or 2.0.
