Seems to work for me, but we're waiting for some testing on a blackbird device, which I dont have.... Anyhow, I'm curious if this patch helps your situation. Patch is located at: http://linuxtv.org/~mkrufky/pending/jelle-cx88-mpeg-restart-queue-fix.patch Let me know how things go... Hope this helps, Michael
