I did a little experiment and found out that the crash is caused by an tv station entry in the zap list.
The tv station causing the crash is AVA Family on the TurkmenÄlem/MonacoSat 52E 10845 V.
As soon this tv station becomes part of the ZAP list and i pull up the zap list with the buttons the box crashes,
i think it has something to do with the used characters/style (Persian) in the program/station information just like Birdman explains i a previous post about the EPG..................
Maybe someone can confirm this ??
