samsung bdp 1000 firmware-getting it onto player??

[HDTV1080P]

You can burn the firmware to a CD-ROM if you want to upgrade the firmware. You then stick the CD-ROM in the player. Further directions are on Samsung’s website.
When 7.1 movies come out your player will down convert them to 5.1. In the future new BLU-RAY players might have 7.1 outputs, also new BLU-RAY players will have HDMI 1.3 to pass some of the advanced audio formats to some of the new receivers.
Your Samsung player 5.1 audio output jacks are used only for BLU-RAY discs. The player will decode the higher bit rate Dolby Digital and DTS sound tracks and it sounds better then DVD. If your receiver can handle the higher bit rate you can also select bit stream and let the receiver decode the audio for you using the digital connection.
There is not much difference between 480I and up converting it to 1080I. I would recommend purchasing one of the new BLU-RAY movies that uses a 50GB disc with MPEG-4/AVC to see how good 1080P looks. The HDTV picture quality of BLU-RAY is better quality then CABLE, satellite, or broadcast.
