Sorry if you feel shortchanged but that's how that jack works. It's been discussed to the point of pain. If this is something you can't stand, return the set. There is no option to change except to use some receiver that does this in place of the set.

As to the frame rate issue, you may have to TRANSCODE the content to something compatible with the set. Some of these tools can bump up the volume as well. Sorry but I no longer support any transcoder. Folk seem to want tutorials and more in replies but I do like HANDBRAKE.
