So I was just thinking that if I had a HTPC unit with a hd reciever card in it and first recorded the program to a hard drive, would I be able to then burn it to a DVD burner and then play back via the pc's dvd? or is the movie to big in megs to do so.
Just an idea

About 15 Gigabytes (15,000 megs) per 2 hour movie.

DVDs at around 5 gigs can only hold about 1/3 of an HDTV movie.

Hard to believe that they can squeeze 80gb+ onto a 3.5" hard disk these days. $230 gets you an 80gb drive that holds about 5 HDTV movies.

It is way more than that. If you take OTA data rate
which is 19.4 Mbps (satellite is even more and go up to
80 Mbps on 36Mhz transponder)2 hour movie would take
a lot more than 15 gigs.

The Matrix in HD recorded to a harddrive via Hipix takes up 17.5gb.

Yes, a bit over 8 Gigs per hour of recorded HD movie on my HiPix. Gladiator, just over 2 1/2 hours, was 20G.

19.4Mb/s = 0.01895 Gb/s

0.01895 Gb/s * 3600s/hr = 68.2Gb/hr

68.2 Gb/hr * 1B/8b = 8.5 GB/hr

8.5 GB/hr * 2hr/movie = 17 GB per movie.

Math never lies. I think this is once again a case of bits being confused with bytes.
