Hello again, I am having more pixeled playback, I don't know how to
explain so I record a video:
http://dl.dropbox.com/u/1541853/VID_20111006_004447.3gp

I get this I2C messages:

My signal is this:

(idle)

There are lots of ber and unc bits, I have connected the TV to the
same wire and there is a good signal.

Thanks for your help.
