stesso problema anche a me da ieri, sul mio clone 800hd ha sempre funzionato fino a ieri con le immagini OpenPli japhar, siccome si era bloccato il decoder ho dovuto riflashare l'immagine, solita procedura installo il driver da pannello japhar. Al reboot non installa il driver. Sembra strano ... Ho provato anche via telnet, ecco i risultati:
opkg
install --force-overwrite v4l-dvb-module-dvb-a867


Unknown package 'v4l-dvb-module-dvb-a867'.

Collected errors:

* opkg_install_cmd: Cannot install package v4l-dvb-module-dvb-a867.
