Bridge cs6 freezes when i select video files

Question

Was hoping someone could help me solve this problem
I just installed CS6 master collection however am having a problem with bridge
even though bridge displays thumbnails of my avi files, every time i click on an avi file to select it bridge hangs/freezes and i have to force quit
this also happens when i select all in a folder that has avi files or other video files in it
it even happens when i select a folder that has a video file in it..it just hangs and stops responding
i still have bridge cs5 installed and it is displaying all files in folders perfectly including video files
the avi files are from my camera therefore they are really all around 1-3mins long
OS: Mac 10.6.8
i7
media stored on external hardrive firewire 8

Answer 1

i followed your instructions and after restarting bridge it actually let me select the folder with the video files...it displayed the first 19 preview extractions with their thumbnails in the content pane in less than a second
then it took 40 minutes to show the next 80 and with these there were no thumbnail preview files
it took at least a minute after clicking on a video file for bridge to select it and tho it did display the metadata there were no preview in the preview pane
after restarting bridge a second time..i encountered the same problem as before...inability to even select the folder with the avi files
i dont know if this will help but these 3 error messages appear everytime it hangs ( i don't understand what they mean but maybe you do)

the other theory i have is maybe it has something to do with quicktime 10 player ?
thanx for all your help so far
