Cube revo- Sifteam R 8873 or E2

i have cube revo twin tuner. tried most firmwares . R 8873 seems most stable for my channel browsing. Still struggling to get sharing through internet working using provider line from my Dreambox config file. NO LUCK yet.

Sifteam E2 would have made it easier for me, but again cannot get E2 working in stable condition yet.

Any Suggestions. Thanks
