Burn small video projects to CD-R System
Maybe this is just obvious, but it never occurred to me until I needed to burn a DVD and didn't have my DVD burner with me. Now we all know that iDVD 5 will save an image file of your DVD project, and with Disk Utility, you can burn that to an external DVD writer, which is great if your Power Book, like mine, is lacking a SuperDrive.

Anyway, I needed to burn a slide show that I could use on a DVD player. I had already saved the image file and I was looking at the size of the image, and it was much less than 700mb. So I wondered what would happen if I tried to burn it to a regular CD-R Disc. In Disk Utility, I selected the image and then chos Burn Image from the Image menu. I put in the CD-R, and with no complaints, it burned a perfect slide show to a CD-R that plays in my DVD player. This will save me a lot of money when I make slide shows for the family -- no more wasting 4GB DVD-Rs for a 200MB slide show.

[robg adds: I don't believe all DVD players will play CD-Rs, so this trick may not work for your particular setup.]

It is correct that not all DVD players will playback from CD-R, but from my testing all Mac DVD players do.

On domestic DVD players, some will play back ok, others will play back with jittery video and audio, others wil refuse to even read the disk.

It was one of the first things I did when i bought my Lacie DVD burner a year and a half ago.
For me the whole point was to give copies to friends and family who only have Consumer DVD playes.

I was so happy, when it worked and played on my mac no problem.
and my DVD Player at Work..

Soon discovered the things did not work in over half of the DVD players.
so then had to go and spend some money on DVDs. grrr

Though it may work in some DVD players, I would recommend against it. DVD video was meant for DVD Media and not CD Media. Why you may ask? Well MPEG 2 (DVD Format) has high bitrate specificatications, hence the high quality. When you burn this format on a CD, your DVD player has to spin the CD faster in order to play it because it physically is the same but holds less data thus wearing out your player's drive.

So you have to safe options:

1) Try lowering the bitrate. (i don't think iDVD allows this, but I know DVD Studio Pro does)

or

2) Use VCD (VHS quality) or SVCD (DVD quality) compression instead. Check out http://www.videohelp.com/ to learn more about it. They know a lot about video compression.

Hope this helps!

SVCD uses MPEG2, thus completely invalidating your denouncement and recommendation in the same statement.

Thx Mike for doing the research. I know SVCD is Mpeg2 but it has a smaller bitrate thus making it good for regular CD's.

This page from videohelp says that miniDVD is not a standard which is another reason not to do it this way.

I highly doubt that any DVD player that reads cd's will spin any disc fast enough to "wear it out" I do believe that if the bitrate is greater than what the drive can acheive, than you will get choppy video or not work at all. For example, if the drive supports 24x cd speed, then 150kbit/s (1x) X24 = 3600k/sec if the bitrate of the dvd video+audio is greater that that, it would fail or be choppy. In no case will putting in a cd with dvd data cause the drive to spin faster than it was designed to. The drive will for sure sense it is a cd.
