Hi,
Anyone having trouble with glitching and freezing with oscam on the VU+ Uno SE try the attached files.
I have loaded many images and many cams and the best I have found is modern oscam emu 1521 cam.
if you install the plugin satvenus-panel_7.0.0 and select other addons download/softcams/arm based softcams/modern oscam emus/ and select modern oscam emu 1521 of the image you are using you are good to go.
Copy oscam.user , oscam.config and oscam.server( edited with your details) into etc/tuxbox/config
if there is no config folder there create a new directory and name it config
put you oscam files in this folder then reboot box.
This has worked very well for me and hope it helps others
