if they are firmware updates by sony for your TR model then u can go ahead and install them but make sure you follow the instructions very carefully else the component whose firmware ur trying to upgrade might not work.
I agree with Rahul. Sony put them out for a reason. If there was no problem, why would Sony have distributed them? I always feel it is best to have the newest drivers/patches/etc. (Within reason. I’m not getting the SP2 upgrade til the bug’s are worked out. Stupid Microsoft, the things that they have “fixed” will take a decent hacker one day to learn to bypass and cause all the innocent software makers to have to fix every little stupid bug from the upgrade for months :evil: )
