HDTV to DVD-R/RW

[itstime98]

I am pretty sure that this is possible but can you capture HDTV with a DVB-T card and then record the video file to a DVD-R/RW at its HD resolution. Not for the purpose of playing it on a stand-alone DVD player but on a PC. Then if you took that DVD-R/RW to another PC would windows media player be able to play this file? or would i have to install a codec to play it because of its higher resolution? Also how many minutes can you fit onto a DVD-R/RW at 1080i?

Thankyou, Adam..

Moved from analog capture to DV forum.

Sorry, wrong forum.

Moved to HDTV / DVB.

if you cut out commercials maybe it will fit but it will be a photo finish , i use a DVB hauppage nexus to cap HDTV , and the files for 1080i are around 5 - 7 gigs per hour

I don't think there are any codecs that'll allow you to play an HDTV Transport Stream recording in something like media player. You'll typically have to use the application that you recorded the program to play it back. I also understand that most computers wouldn't play the HDTV recordings very well anyway unless they had the proper hardware decoders (the card you record with likely does the decoding to play it also, as opposed to using your CPU and some software).

As far as putting them on a DVDr, I've been able to fit 22 mins of HDTV from ABC on a single DVDr, but just barely, and it meant cutting the commercials -really- close to the actual show. That may sound like a good thing, but the way AC-3 audio is stored in the transport streams makes it difficult to accurately trim the raw transport stream. You really want to leave a couple seconds (5 or so) on either side of a commercial break, or you risk loosing some of the audio.

So at the moment, there isn't really a good solution for storing HDTV recordings, unless you feel like splitting it over several discs. But that's why I have over 400gigs of drive space ;]

On a fast computer neweer WinDVD versions will play transport streams but you have to first rename them to .trp.

It is possible to take 1280x720p or 1920x1080i DVB-S captures and convert them to WM9 and burn it onto DVD-R. A <2 hour movie can be compressed with little apparent loss.

But I said DVB-S and not DVB-T. None of the broadcasters in North America use DVB-T. They use ATSC for over-the-air broadcasts. Capture software for ATSC cards gives an ATSC transport stream and not a mpeg stream, but the conversion is similar with only the first few steps being different.

What broadcaster do you wish to capture?

this is for Australia,
Digital television will be transmitted with MPEG digital stereo sound and/or Dolby" Digital Sound (6 channels)

What things would i need to do to recompress?

[Shameless1]

What tools you need depends on what your DVB-T software captures as.

Here is a link to another forum where it works for .TS, VOB, and Mpeg2.
AVS-WM9-VCM Method (http://www.avsforum.com/avs-vb/showthread.php?s=&threadid=255043)

Also if you haven't chosen a card yet, or want to know about software for it, I suggest this forum (http://forums.dvbnetwork.com/viewforum.php?f=29)

Also once you have the stuff captured, others here would be able to help more. I follow the steps in the first link, but I don't understand them all ;)

Cheers,

Shameless.
