Burn small video projects to CD-R
Authored by: spiffyguy on Mar 31, '05 03:48:21PM

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.
