Anyone know how many minutes space does HD take up on DVD?

It will depend on bitrate. Max file size will always be at 4.7 GB for SL or 8.5 GB for DL.

What type of HD are you talking about?

Is it HDV at 25Mbit/s CBR?
Is it HDTV at 19Mbit/s max VBR?

I have Sony HDV camcorder and when I capture one hour tape to my PC the file size is about 12+ GB. So, I can fit about 20 minutes on SL DVD or 40 minutes on DL DVD.

I also recorded a bunch of movies from HBO-HD. Some movies are under 8.5 GB and will fit on DL DVD.

Roughly 35 minutes of ATSC rate data depending on how it is packaged.

I can fit a 1/2 hour TV show on a single sided disc no problem in HD DVD or BD format. Though that is 20-24 mins and max rate 19.4 Mbps.

there is no point putting HD media onto dvd since the dvd player cant read pas 10Mb/s.

Actually both the Toshiba A1 and the Panasonic BD player can read ATSC data rates of a DVDR disc that is correctly formatted without any issues.

Ditto for PS3.

Huh, the question is how long he duration of an HD video can you make on the DVD medium. Obviously for play back on a PC. However there are rare DVD players that have Divx Ultra capabilities, which can play HD encoded Divx video files, though it must conform to Divx Ultra specifications, which does not give much flexability. In other words you can't just burn any old HD divx file on to a data disk and hope it will play it. You most likely have to re-encode it to Divx Ultra specs.

If you are good at encoding video, You can compress a DVD 5 movies, at near source quality in a file that is 1.5GB using Divx or Xvid (you could compress it to fit a CD but then you will loose a lot in quality). Thats a compression of 3:1. Not bad.

Using this logic you should fit a 15GB Mpeg 2 HD movie. (broadcasted HD content is Mpeg 2)

, via mpeg 4 compression on a DVD9. Just note that Hd movies on disk are being encoded using mpeg 4 technology (BD movies use Mpeg 2, but AVC seems to becoming more common, and just may relpace mpeg 2 on BD), which make it more difficult to compress without loosing major detail.

You can use the wizard in VideoLan to 'repackage' a TS file as a MPG ps stream (no re-encoding so it's very fast). The resulting MPG plays just fine on the PS3 if burned to a DVD ROM. Most movies will fit on a dual-layer DVD+R.

The one drawback is that the Dolby Digital soundtrack is currently played back in stereo - there are rumors this will eventually be fixed.
