wierd video issue

87W (SES2) 11960 H 29269 3/4 DVB-S, sid 6, pid(s) 1600/1601/1600

No video but there is audio (AAC).
When I go to the menu / tv channel list to edit, the picture shows up in the preview frame.
Go back to view, no picture comes up.

Tried re-booting, changing sats then back, etc... persists.

I don't think the stream is scrambled. Is anyone else reprodicing this issue?
