[opendtv] Re: Q on digital OTA broadcasts

Notwithstanding Ron's comments, there is the capability to send "copy once
only" in the XDS data that can be embedded in CEA-608 captions.  CEA-608
captions are MANDATORY in all ATSC video streams.

There is no capability to send "copy once only" otherwise in transport
streams.

Ron and I answered different aspects of the case.  If you think that what he
says trumps my comments, you might end up being surprised.

Good info, Ron. So maybe there's no problem after all, at least for OTA
users.

Here's the wording in the owner's manual:

http://www.p4c.philips.com/files/d/dvdr3575h_37/dvdr3575h_37_dfu_aen.pdf

On page 39:

"You cannot record copy-protected program using this unit.
(Copy-protected signal is included in DVD video or some satellite
broadcasts.)

"You cannot record 'copy-once only' program on DVD."

On page 115:

"This unit cannot record programs that contain copy protection signal.
This is not a malfunction."

Could be that the mention of "copy once" only applies to NTSC
broadcasts. Could be that the rc descriptor is explicitly ignored. Hard
to tell.

What I would have preferred to see is an unequivocal statement that says
that any program can be copied to the HDD, no matter what settings are
broadcast, but that copying from HDD to DVD may be prevented. And then a
list of circumsances where this is the case.
