Two new problems

 I have the following problems and I wonder if they are related to the previous firmware update:

  1. The player is connected via HDMI to the TV. Turning the player on with the remote (from sleep mode) is not successful (though the status light in front is on), Only dis- and reconnecting the power cord is successful.

  2. When connecting with a USB stick, all possible formats (JPG, AVI, MKV) are reported as unknown or unsupported. (library is always turend off). After waiting 30-40 seconds the player is playing all files without problems.

Any ideas?

Have you tried resetting via the side button using a paperclip / cocktail stick with the unit on and fully booted up. Press for 1 second and then let go - the unit should reboot.
