The TV encoder used on this board is a VT1625 and there was a patch
posted to enhance VT1625 supportsome time ago, but it was not reviewed
yet and thus not committed to SVN. However, some people tried it and
reported success, it might help with your issue.

The original patch doesn't apply anymore to trunk, I'm attaching an
updated version.

Xavier
