Hi Jörg,

Yes, it's all available on the *magic* J2 connector ;o))

>Second, I am not sure if you can use RGB on every television

This might be. Although since RGB is the TVs native mode,
it makes me wonder why manufacturers skimp here (I mean
it *is* a sales argument)

>I am not really sure if the signal is always displayed correctly
>on TV sets.

I can adjust this on my Thompson. My Nokia 9902 also has
some features to be able to shift the RGB picture to fit the
TV set.

>much visual difference

I *assume* those that see a difference (I don't see much of a
difference on a normal TV show), are seeing this *not*
because the DVB output is much better, but probably because
their TV set can handle Y/C better than FBAS (as this too
bypasses some of the TV circuitry). Most definately the RGB
picture is much better than composite.

>users should build a special cable for their J2.

The real problem with J2 is that you are "handling" the fragile
ARM-7 outputs directly. Many people have killed their DVB
that way. My DVB extension board (Rev 2) will prevent this.
The piggyback adapter, which Thomas Breuer and I developed
should prevent this in the future. As soon as this stuff is
"buyable", I'll let the list know.

Greetz,
Reinhard
