[libdv-dev] DV export success!

[Alastair M. <ala...@ww...>]

The 50_60 flag makes a *big* difference exporting to a Sony TRV103 NTSC
camcorder, thank you Yamazaki and Dan.   Changing the CIP timing to 1, 16
(ie 30.0 frames/sec) cleans out some block noise with that camcorder too.

My camcorder now seems rock-solid on export with the 50_60 flag set
correctly and the framerate at 30.0.  Framerate at 29.97 gives an image
but with periodic bursts of block noise, so this is certainly something
that needs to be user settable for different equipment.  It'd be nice
to build up a database of which settings work best with which hardware.
(And perhaps have the software default the settings based on the hardware
IDs from polling the device.)

The above successful testing was based on modifying dvconnect (in libdv)
with the changes suggested for Kino -- I haven't tested the latter yet
because of the required kernel module change.

Thanks guys.
