Why is 9.8Mbps the Max bitrate?

Using DVD Architect 4.5 to burn a DVD - the max bitrate it allows is 9.8Mbps, even though I have a lot of extra space on the disk. Would like to understand why this is the case.

Thank you for your replies.

This is because the maximum bitrate for DVD is 9.8 Mbs.

If you want it to play on most newer players you shouldn't go over 8 Mbs.
If you want it to play on most older players you shouldn't go over 6 Mbs.
These are general guidelines, and shouldn't be taken as exact limits.

Thank you for your reply.

I have been using max (9.8Mbps) on my DVDs, and they play on
without any problem on my (Sony) DVD player - I didn't know anything over 8Mbps could cause a problem on other players!!

Guess you always learn something new every day.

9.8Mbps is the maximum total of the audio and video combined. All DVD players are supposed to be able to play discs at this rate but, in the real world, the maximums are considerable less, particularly with burned discs.

Bitrates higher than 8Mbps only add to the file size, not to the quality. See http://www.mediachance.com/dvdlab/tutorial/bitrate.html
