Is NGHD supposed to be "Copy Never"? I cannot timeshift it (won't record).

When tuned to the channel, my TV always displays "Copy Never", so I'm assuming this is why I can't timeshift.

On what service? I record NGCHD on DirecTV all the time and used to with Comcast (can't right now as removed my SA8300 and put in an HD Tivo, but haven't scheduled cablecard install yet).

You mean it's supposed to differ by provider?

Comcast w/cablecard.

Yes and no. The "Copy never" flag may (or may not be) in the stream from Nat'l Geographic but until the provider's software recognizes it and honors it, it will ignore it and allow you to record. National Geographic, or other networks, don't have unique streams to Dish, DirecTV, Comcast, Time Warner, and so on.

I just recorded a minute of Nat Geo with no problem (on Dish). Dish has been testing, but doesn't currently have copy-protection implemented on their receivers (yet).

Just curious....are you using HDMI or Component to get the signal to your TV?

Comcast cable to TV QAM tuner using Motorola CC.

TV is displaying "Copy Never" when tuned to NGCHD during any program/commercial, even when not trying to record.

Fully DTCP compliant IEEE1394 HDDVR (http://www.indigita.com/products/customsolutions/avhd.html)

Does anyone have an STB that's able to confirm this.

Strange thing is that on my cablecards conditional access menu (when tuned to NGCHD), it displays "Copy Protection Key: disabled" and "CCI: 0x00".

Maybe the cablecard is setting the EMI bits or imbedded MPEG CCI bits in it's decrypted output stream to the TV?

BTW - It's a 2007 Mitsubishi WD-57831.

Sounds like a configuration error on your Comcast system.

I thought the broadcast flag had nothing to do with cable, wasn't enacted and cablecards ignored it if present?CableCard Tivos ignore the broadcast flag. For whatever reason, the current firmware on most Motorola and Scientific Atlanta DVRs is set to observe the broadcast flag. That's why many using cable company DVRs can't output FOX HD recordings via IEEE1394.

If you are using a CableCard in your TV, it is possible that its software / firmware was written before the broadcast flag was struck down. In other words, newer CableCard TVs and third-party CableCard DVRs ignore the broadcast flag, but older ones may not.

Why would the "Broadcast Flag" be set on NGCHD. It's not an OTA broadcast.

I guess what I'm trying to ask here is, "What is the intent of FOX/NGC." Are they trying to prevent me from timeshifting?
Are we supposed to be able to timeshift NGCHD programs that are stored encrypted on a secure device?

Can anyone else timeshift NGCHD content?

If so, I need to be talking to my TV manufacturer, my PVR manufacturer and Comcast to find out what's wrong.

Are they trying to prevent me from timeshifting?The flags do not prevent you from time shifting, provided you have a cable company DVR, TiVo, or a even an older CableCard TV and 5C compliant recorder with a proper implementation of the broadcast flag.

Are we supposed to be able to timeshift NGCHD programs that are stored encrypted on a secure device?

Can anyone else timeshift NGCHD content?I timeshift NGC-HD content. I timeshift it on my Tivo (http://mysite.verizon.net/~fiosdvr/tivo/nowplaying3.jpg), download it in high-definition to my PC (http://mysite.verizon.net/~fiosdvr/tivoweb.png), automatically remove the commercials (http://mysite.verizon.net/~fiosdvr/videoredo/videoredo3.png), and burn it to DVD in HD-DVD format (http://mysite.verizon.net/~fiosdvr/author/import.png) or Blu-ray disk.

If so, I need to be talking to my TV manufacturer, my PVR manufacturer and Comcast to find out what's wrong.I would guess your TV manufacturer. They are observing that flag when they should be ignoring it.

Well, now I'm getting the same thing on A&EHD. Never tried to record that one before. Another Fox distribution.

What's wierd is if I do an "immediate" vs. timed record of either A&EHD or NGCHD, it will appear to record for a few seconds, but when I play it back it's in SD and all I see full-screen are white letters on a black background stating "We're sorry, the program you are trying to watch was time limited and has now expired". Wierd because I play it back within a minute of it recording. Time limited to what? 5 seconds? I thought the minimum retention time for Copy Never content was something like 90 minutes?

Nobody else is seeing this?OK, how about just someone with a STB. Can you tell me if the RC (Broadcast) flag is set on these channels?

I assume it would be systemic across all providers if Fox Cable Distribution sets it.

A&E and History channel HD typically have the EMI "Copy Once" for me. They allow me to save the M2T transport stream, but then not play it on my computer or convert it to mpeg4/h264 to save. This has been bugging me for months now since MOST HD stations are open to copy and save. Science HD is always open for me, even Universal HD allows all of their movies to be saved and copied freely.
Anyone figure this out? I have an 8300HD, sending it to my computer via the 1394a port, in central florida with Brighthouse Networks. I thought it was just an error with my provider that I've been bitching about.
The standard def channels were always open.

However...I just noticed a Fox theme here. I'm always able to save and edit M2T's from all FOX shows...even football games. I DVR them, then I can email them to my brother at his dorm (doesn't have an HDTV, but has a 30" apple monitor like myself, which looks pretty darn good...I saved the superbowl as 720p H264 at 10mbps and it looked pretty perfect...no huge artifacts, and i'm super anal). The EMI for FOX comes up as "Copy Freely" for me, although national geographic hd, a&e hd, TBS HD and history hd are usually "Copy Once".

Is this while tuned to the live channel, or do you somehow get that status for a recording you made and are viewing?
I don't have a STB. I have a DCR TV with a Motorola cablecard. My DVR (attached to TV via firewire) won't record and displays that the program was time limited. My TV displays Copy Never status when tuned to A&EHD or NGCHD but the cablecard conditional access menu shows "Copy Protection Key = Disabled" and "CCI = 0x00" on either channel, which should be Copy Freely. The cablecard menu does not display the EMI or BC status.
