[QUOTE="globaldonkey, post: 617032, member: 49844"] Do both. Start with getting rid of any existing codec packs, then upgrade to the latest Catalyst, then load SAF. Pay attention to best practices for uninstalling old Catalysts too, before installing the new one. ATI's uninstallers, particularly the older ones from the 8.x era, typically don't do a good job, and you'll want to use something like Driver Sweeper or Driver Cleaner.net to clean up after the mess they leave behind. Catalyst uninstall / reinstall (over several versions admittedly) left me with broken DXVA. On two separate systems. PS implement a good backup strategy (and test it) before you do all this so you can get back if it all goes pear shaped. The general process I would recommend would be: 1. Backup 2. Uninstall existing codec packs, such as K-Lite, PDVD9, CCCP etc 3. Uninstall Catalyst (via ATI uninstaller) 4. Reboot (you'll be back to a horrible looking windows default video driver) 5. Run driver cleaner or driver sweeper (select clean ATI drivers) 6. Reboot (yes, do it again) 7. Install new Catalyst 8. Install SAF [/QUOTE]
