oscam live log:

error key not found

but i put softcam.key in same directory as oscam.conf as in tutorial

key found but heavy pixelation and picture freeze on dm800hdse:

P 0047 00 113754C6C0CEE100 ;LePLEX HD ,105.5°E 4180-V-30000
P 0047 01 785E6AFF44D7A900 ;LePLEX HD,105.5°E 4180-V-30000

can finetune the performance by tweaking the config?

or due to dm800hdse cpu not fast enough?

thanks
