256kb vs 512kb data buffer in DVD-ROM drives: will you see any difference when playing DivX avi files and with games?!

Hi,

I've noticed that some DVD-ROM drives have a 512kb data buffer instead of 256kb. When will you see a difference? Will I get better performance with 512kb data buffer when playing movie files (avi, mpeg) from a cdrom in my drive or when playing games that perhaps also need the cdrom drive, or is a 256kb DVD-ROM drive more then enough for those purposes?!
I don't intend to play DVD's, I will just use it as a CDROM drive but wanted to know if playing games or video files (avi, mpeg) from a cdrom will benifit from a drive which has a 512kb data buffer compared to 256kb?! Will avi files that use the DivX codec benifit from the 512kb
data buffer, since I believe the requirement for smooth playback of DivX avi files from a cdrom are higher then normal avi files, but I don't know if a 512kb vs 256kb data buffer has much to do with this?

Anybody could please explain this for both games and video files (DivX avi, mpeg) on cdrom that play from the drive? Thanks in advance!
 
Could anyone please explain *WHY* the data buffer (512 vs 256kb) is or isn't going to make a difference for both playing games and DivX movie files directly from a cdrom in the drive, especially since I thought that DivX encoded movie files have high requirements for smooth playback or has the data buffer of your DVD-ROM drive nothing to with that?! What's the technical reason?

Thanks for the info!
