I just found out that the TD20 does not accept the aftermarket FV100 3900 Amh battery I purchased for the XR550. It seems to work fine for about 45 seconds, but then an error message pops up - "For use with compatible battery only" - then shuts off automatically.
I never used to purchase Sony products due to their MMC (duo, etc..) proprietary slots. I started to let my guard down since they incorporated SD card lot into their products. That guard is going back up today when I found out that they put something in the TD20 to detect the aftermarket battery and purposefully not accept it to compel me to purchase their Sony battery.
I'm thinking about returning this TD20.
