3 edits | [ TV] Capture from HD Cablebox via FireWire
Discovery HD | 
TMN HD |
But anyway, here are the two tutorials if anyone wants to read them:
Mac »project-tigershark.com/people/ro···e-hd-pvr
PC »hdjunkie.com/tutorials.html
The results are quite amazing, I've attached a couple screenshots. Also I've included a list of channels that are not encrypted, and the ones that are encrypted which do not work. This is a list from the GTA, so if you're in other areas the channels or the numbering may be different.
Edit. All SD channels are unencrypted so they can be captured at their normal SD quality as well.

I heard that the 8300HD PVR has firewire port disabled, but a new firmware has been distributed recently that not everyone has gotten yet, that supposedly enables the firewire port. If it does, I don't see why it wouldn't work.

Port Coquitlam, BC | How about the other ports on the HD PVR's?
I would love to be able to plug a bigger Harddisk in!
I will have to try the Firewire recording!
Thank you

Are those pictures a direct screenshot from the actual HD feed and are they in their original raw picture format? cause they seem to look a little blurry to me.
I'm interested to know, thanks. |

They are a little grainy at times.

kudos:4 | Still shots aren't really representative of how good the live picture looks, even less so when viewed on a computer monitor (where they appear much darker than the original). Discovery-HD, in particular, is usually just stunning in its clarity.
Anyway, this looks very cool -- unfortunately I have no computer currently with firewire, but the idea of building an HD-DVR out of an old computer is kind of intriguing.
I'm puzzled by the list of encrypted and unencrypted channels, though. My understanding was that in the U.S., the FCC mandates that all OTA channels must be unencrypted on cable, but this is not the case with the CRTC in Canada, and that Rogers chooses to encrypt ALL HDTV channels.
Your list seems to contradict this, which seems strange, and even stranger that premium channels like Discovery-HD would be unencrypted while some broadcast channels are encrypted!
"Rogers does offer a modicum of free unencrypted channels than these QAM tuners can pick up even without a Cable Card installed. Alas none of them are high definition – since Rogers charges for the HDTV tier – but something is better than nothing."
»www.remotecentral.com/hdtv/rogers.htm
I wonder if what the Firewire allows you to output is related to something other than encryption. Either that, or something has changed since the boys at remotecentral made that statement.
I do have a QAM tuner and I might try hooking up cable directly to the TV and see what I get. Unfortunately everything is set up so nicely I hate poking around behind the cabinets and messing with cables in the dark! |

| Here are some screenshots from a 1280x720 progressive stream, a show on ABC called Knights of Prosperity. They look better than the 1920x1080i ones because there's no need for deinterlacing.

I used to do a lot of capturing back in the day.
Are there any breaks in the stream when recording/capping? Also, does it use alot of CPU load when capturing as well? |

I've yet to measure CPU load. I've been doing it on a 2ghz CoreDuo Laptop with 2GB ram with no problems. Today Im gonna buy a longer firewire to test with my PC, which is a Dual Core 2.9ghz AMD with 2GB ram as well.

HAve you had experience with the 8300HD? I've been following the digitalhomecanada thread regarding it, but people have had more success on the 3250hd.
I have a lot of stuff on my PVR i want to get out and save the pure digital stream. |

Well I hooked up the cable directly as I lent someone my hi-def cable box for the night, and the only digital channels I can get are the unencrypted ones listed in the previous link. So I don't believe any HD channels are unencrypted -- I think what is or is not allowed to come out of the Firewire port is related to some other restriction. Anything other than the ones listed as unencrypted (in my link) gets a "not authorized" from the QAM tuner.
If anyone has a QAM channel number (not a cable box channel number) of an HD channel they believe is unencrypted I can try it, but I do believe the only free HD around is OTA via antenna. Encrypting local broadcast channels on cable, HD or not, is actually illegal in the U.S. |

Can you capture from recorded programs or just live ones? I have a show I'd love to take some excerpts from on the HD (my wife appeared in it)... but no real way to do it. If this would work, I'd move the iMac downstairs for a bit to do it.

It works on both live and recorded programs and not just from the 8300HD PVR - it will work from the 3250HD box at least as well.
Some channels are encrypted and some are not. You can only do this with the ones that are not encrypted.
I don't have the new firmware on my boxes yet but it is supposed to be this week in Ottawa. |
