If it is working on your other boxes (eg 500hd) - copy the plugin and folder /etc/epgimport to this image. Then in the plugin file epgdat,py - change endian "<" to ">"
Then it should work ok.
Also in /usr/bin/enigma2.sh change cp to mv -f in the epg.dat line. Then you will not see epg_new.dat again.
Other matters - code changes required for jpg.
For tests and development - I use BA multiboot.
Sorry I do not have much time to work on this image. Also I am getting old !
Cheers, pcd.
