Backing up HD mpeg file to DVD?

[trlowe]

I apologize is this is a bit off-topic but it didn't seem to fit anywhere else any better. I cannot seem to find an answer to this question anywhere else. Hopefully someone can help here.

I have a High-Def MPEG movie (1280x1088) on my hard drive that I would like to copy off to DVD. It is a bit over 8GB. It is my understanding that you have to have special drives that support HD-DVD for that, can I at least copy it to a "regular" dual-layer DVD as an MPEG file and maintain the quality? This will allow me to store it until I can get an HD-DVD burner.

yes you can save the file as data.

As Ed said, but the file should be split up in 2GB chunks for best compatibility. Correct me if I'm wrong (and boy, am I wrong frequently), but most burning apps will insist you burn a DVD in UDF file format if any file is over 2GB. That's fine for most (but not ALL) systems. My only concern is compatibility, so I err on the side of caution and split the files up.

UDF usually reads fine on a computer. A typical HDTV MPeg2 TS file (16-25Mb/s) fills a DVD in 20-30min. WMV-HD or other MPeg4 can get to around an hour.

Most HD TV broadcasts run around 13MB/s. I am doing a lot of HD recording off of Leno, Conan, and SNL. That is with 2 channel AC3 @ 384. A good way to archive larger shows is to seperate it to multiple discs using a program like WinAce that will zip the file into parts that fit on the DVD, that is if you are planning to just archive and not play off the DVD itself.

They run 13-14 MB/s when an additional simulcast SD channel is in the mux. The TS stream should include both at around 19Mb/s. Cable is devoting 20-25 Mb/s to single channel HD feeds.

After reading this and looking at a channel I saw that. Old SD material upconverted, Friends reruns, are showing as 19.1 where HD material is running 13 so the simulcast is in there. Wish they would run straight streams of HD content and give a little more to lessen the compression.

You can use HDTV to MPeg2 to extract a single stream.
