Well every release is out to add functionality or fix issues, but they always add new issues to the mix.
The new update did fix some very bad issues. Command queuing is not an issue, overall performance and channel surfing is much quicker and operations are better. Clipped DVR recordings instead of not recording a show at all (due to a nasty 10:01 end time on a program when another show starts at 10:00, and both tuners are active). More ratings information in the guide, 3rd party application support (for games, caller id apps, etc...) and a few little things here and there.
But, of course with all the pro's come all the con's. Firewire output appears broken, HDMI issues are showing up for some people, and general graphics issues. Go into VOD and play a preview of a movie. On my DCH box, every time the menu's will be all screwed up after playing a preview. Also when you play VOD the screen screws up while it says "One Moment Please". They still didn't add native HD resolution pass through, or auto switching (720p on appropriate networks, while 1080i on other appropriate networks), and of course you can't expand the hard drives yet.
So with each minuscule improvement, there are always new bugs that show up.
