I already posted about this issue also in ViX forum because the it affects also ViX 5.4.008. I found out that only in the two submenus Setup/Recording, Playback & Timeshift, is not possible to go down in the options list. It happens only in these two submenus, as far as I know and, obviously, it does not depend on the RCU because 1) it does it with every RCU units I've got; 2) It does it also by OWIF. 3) It does the same also in OBH 4.4.008. So, remembering the other issue discussed some days ago in the Tuner terrestrial scan, I tried replacing Recordings.pyo and Timeshift.pyo from older images. Replacing the two files above mentioned taken from 4.3.039 in /usr/lib/enigma2/python/Screens at least Timeshift submenu works, whilst Rec&Play crashes. I then tried Recording.pyo from 4.4.001 but it's the same. But the issue it's almost surely due to some change in these two files or also some other ones. Surely it is because of Timeshift.pyo.
