OK. On the retry, if I replace the /video0 with /video1, it works. So far, so good.

Adding the fps=25 in the tv: command was allowed, and again it ran until the video buffr filled up, but the flickering is still bad. It might be a bit better, but not significantly. Whew! -- Davey.

Hmm, only showing 15fps this time - maybe you are after all running out of CPU. What does running top -b | grep Cpu show while testing? > Changing the 30000/1001 to fps=25 didn't work, it insisted on the > xxxxx/xxxx format. Oops, my mistake I should have said -ofps 25 If you are running out of CPU then it's not going to help anyway :-(
