[fil_mac]

Hello,

I've just bougth a new pc (HP Z600 workstation - Intel Xeon 2.4 Ghz -2 processors - 12GB RAM) and i'm working with windows 7 64 bit. I've instaled protools 9 and everithigs is working fine with audio. But i have a problem with video. I've instaled the quicktime for 64 bit version but it doens't open. I double click the shortcut and it simply doesn't react. When i open protools and i try to import a mov video the system cracks to. Just doens't work. Something worong is hapennig with the video files when i try to open it with Windows Media Player. I get an error message and it dont work. Can someone help?

You may want to try installing QT for 32 bit as Pro Tools is still a 32 bit program.

That makes sense but i'm not sure if that will work because quicktime is automatically instaled with itunes. The itunes 32 bit wouldn't work on my machine 64 bit. I tried and i get this message saying that was detected that i had a more recent version of itunes in my system (even thoug i have unisntaled it).
But i'll try again and see.
I have some issue with basically all my video programs and i don't know why. even the Windows Media Player is not working. If i try to open videos it cracks and i get this message saying that the program stopped working. If i open audio i can listen for some seconds and after a while i get the exact same message. I don't know what to do.

Can someone help me to figure out what's going on with my system?
Could it have something to do with audio codecs incompability?

Just to say that my problem was solved by updating the BIOS in HP Web site...
