Tried all the buttons. No "menu".
No 15 sec (or any other interval) skip either. It will do FF and RW up to 32x, chapter skip, and you can go to a specific time in the movie (it requires about 20 button presses to select a time, but it's doable), but no quick skip.
Infuriatingly, there is
a "home" button (labeled menu) on the front panel of the unit itself, but no equivalently functional button on the remote.
The remote is not well designed at all. In addition to the missing home and menu buttons, the 5-way cursor buttons (what you use to do 95% of menu navigation) are too small and close together to be comfortable. The entire bottom row of buttons are basically useless. All they do is select what type of files are displayed in the menu. Only necessary if you throw all your different types of media into one folder, which nobody does.
Looking at the Xtreamer forums, they're having a lot of issues too. The rep claims they will have a new firmware out in the next day or so. I guess this is what happens when two companies are more concerned with one-upping each other on release dates than one-upping each other on quality.
EDIT: More bad news. Just tried this 1080p / DTS blu-ray rip sample
. Playback stuttered over 100mbit wired network. Tried a USB stick and the video played fine, but no audio. I guess this means no DTS downmix.
