on March 2nd 2008 I was von LH 459 SFO-MUC. I was lucky to get D-AIHP which had a PTV system installed in Y class. I was on seat 52H, and as an IT pro I'll give you a review of the installed system (right now being deployed throughout the LH longhaul fleet according to the crew). Please forgive me if it gets all to technical.
Executive summary: the system is quite okay, but still has some flaws.
The screen is a touchscreen. On some screenshots, you might see white or dark pixels arranged in a pattern. They are holes in a plastic foil that coveres the entire screen and provides the touch input. The holes aren't that much noticable in real life. Below the screen display area are two fixed buttons labeled "on/off" and "menu". The old controls for audio, TV and reading lights were still installed in the arm rests. Last thing, the screens are attached with an analog interface, resulting in slight color distortion all the time. Sorry, no DVI here folks
This is the welcome screen that was visible on all screens during boarding. Please note the yellow mouse cursor: the effect is neat (better visibility on white areas), and the shape is evidence for a Windows based system.
After tipping the screen, the language menu appears. I've chosen German as language, although English would have been better for this report - sorry
This is the main menu of the PTV system. Different areas can be accessed through the menu on the darkened area on the left side. The last menu option is "turn screen off", which does exactly that. Music or a film wouldn't play with the screen turned off.
Another option is the screen brightness which can be adjusted here, and only here. There are no separate buttons below the screen or in the armrest to adjust the screen brightness at any given time, like on JetBlue systems. The lowest setting for brightness does not turn the screen off, you have to use the option mentioned above for that.
The first option is "Fly Lufthansa", which contains information from the inflight magazine.
On my flight, there was a ca. 20min film about the A380 route proving program and its integration into the LH fleet. I found that video more entertaining than any other movie on offer, and actually watched it twice . The screenshow above shows the pre-replay screen for every video and movie in the system. It contains a short description and also a language selection. The language selection did not work properly for me, mostly only one language (German) was available. Probably that was tied to the overall language selection for the PTV system.
Other options from this submenu take you to different pages that present information about Lufthansa and its fleet (click on thumbnails above).
This is the submenu for watching movies. Please note the unusual page bar indicator (like a scrollbar) in the top right corner. Menu pages are changed with the arrow buttons at the lower end of the screen.
At the start of each video/movie, the menu above appears, to change screen brightness and volume. To end a movie, you have to use the ON/OFF button below the screen, and press "yes" in the dialog box that appears. MENU takes you immediately to the submenu, or if pressed in a submenu directly to the main menu.
The inflight map is also available. Unfortunately, the PTV system simply switches to the TV channel for that. Your music will NOT play while watching the inflight map because of that (again that's what works on JetBlue). Instead of the previously played music, a standard lounge music is played during the inflight map. Additionally, the inflight map is not found under "Watch", but under "Fly Lufthansa" and then in the "On board" submenu. Adding a link to the "Watch" menu is definately a todo.
