To Odyssey:
I'm not agree with you. I reckon that many people upgrading firmwares only because they have the hope to have some improvments or bug fixes. I would like to underline that some mp3 or dvd player are put on market with a lot of problem (such as a poor file management, casual system crashes, etc..). So a user look for a solution on the internet and, unfortunately, in several cases the firmware upgrading fails.
This is also a fault of manifactures which put on market incomplete products because they are pressed by the laws of market. Moreover, they in several cases don't support the final user with official new firmware versions (except famous manifactuers).
