Hi all

I am a novice on the satellite scene, so apologies if this post is not appropriate or posted in the wrong area.

I have installed SMARTDVB on a Windows XP PC (AMD Athol 2.2GHz dual core, RAM 3GB, Haupagge HVR-3000) and HADU plugin, all latest available versions.
When I look at not encrypted channels all is good, but when I look at encrypted channels the video and audio are clear, but choppy.

What could be the likely cause? Have I missed anything in my configuration?

I have tried installing PROGDVB, but the video is even choppier...

Thanking you in advance for all you help.
