Thanks for your mail. The scan files have been split out into a separate package called dtv-scan-tables. Therefore I am reassigning it to d-s-t. Oliver Schinagl (CC'd) is the upstream dtv-scan-tables maintainer. I have reattached your cz-All-actual-2013 for his consideration. Thanks, Jon Signed-off-by: Oliver Schinagl <oliver@schinagl.nl>
