With the number of standalone BD players growing all the time now, keeping up with the latest firmware/software updates for individual players is getting harder and harder. So this is an attempt at having one thread that allows everyone to check and see if a new update is available for any standalone player (U.S. models only).
The latest firmware version and release date is listed to the right of each model number. The model number itself is a link to the manufacturer's support page for that player, where you can download the latest fimware/software for your player. Most updates are provided as a CD or DVD disc image which can be burned with most PC recording software.
