Has anyone noticed the vertical blank spot on "off air" HD broadcasts with the DTC-100?(I am not in range) The blank spot occurred for me on only some of the programming on ch199 and only some of the movies on HBOH. The point I'm getting at is that perhaps DirecTV is sending us the blank spot as the result of a non-standard mix of HD source material. It would be appreciciated if someone could verify the same phenomina on "off air" broadcasts as well.

Thanks,
Ron
