Sundtek SkyTV Ultimate - DTV_CLEAR failed [e=Success]

You can try to switch to isochronous

/opt/bin/mediaclient --transfermode=iso -d /dev/dvb/adapter0/frontend0

replug and test.
The default mode is bulk (–transfermode=bulk) would switch back to the original mode.

however there was a bug on some amlogic devices (definitely not on all of them because we’re using an amlogic Android unit without any problem).
We’re about to release the android driver next week (no rooting required and it seems to work well).
