The reason why I am very interested in modifying Samsung firmwares is, that I currently own a PN50C550 and a Blueray BD-C5500. Next year
I will return to Europe and I plan to take them with me. So it would be good, if i could use them in Europe, and modyfiing firmware is one step to this. (I know
that it would not be possible to use the tuners, but the Set should work using HDMI, as I have a Sat-Receiver using it.)
This is how my Info Screen in Service Mode looks:

I got extended options in the service Menu after enabling and disabling Hotel Mode. This is what I did:
Enter Service Menu using : Mute - 1 - 8 - 2 - On
Go into "Option"
It shows this options:

Go into "Hotel Option"
Enabling Hotel Mode
Then "Clone USB to TV" (to get a current channellist)
After that i Disabled Hotel Mode
Pressing "Exit" to get into Option Menu again
Then it looked like this:

and I got much more options when I entered the Sub, Config and Sound Submenus:



I enabled PVR Mode, but I cannot see a difference. How can I check if this is working?
Thanks for all the work
Bye habee
