speed//Buffer//DMA

[Preppens]

I dont know where to start, i have tried everything and read every page on the internet .

My problem is that the device buffer is never reaching 100%, (readbuffer 100% tho) never over 90% pending from 30-90% and the writingspeed is pending 4-9X when the burner and the media supports 16x, and the quality of the movies im burning is sometimes crap, sound dissapering, glitching, freezing...ahh...you know what i mean. If im doing something else on the computer when im burning, just opening a map, both buffers going nuts and the writing speed goes down...

To make it easy i removed all hardrives but the system drive and that is a Hitachi Desktar (older) 60gb for the moment, put to primary master, (tried with my s-ata drive and other drives as systemdisk) so its nothing wrong with the disks.

One dvd burner philips dvdr 1640 (latest firmware) set to primary slave(i have tried to set the burner to secondary master,slave etc.), tried other burners Nec, Sony etc. so the burners cant be the problem, im using good media (verbatim) but i also tried with other brands TDK, Sony, etc. so that cant be the problem. . DMA is enabled, 32bits transferrate in bios enabled, tried different burn applications, nero, clone...etc, neros aspi...

Burn something and show us a screenshot of the IBG file within DVDInfoPro.

 

It's normal for BenQ drives to have their buffer sitting at 90% all the time. Mine never reaches 100% either.

 

Are you using an 80 wire cable for the connection between your motherboard and the burner?

 

What's your CPU% usage at whilst burning?

 

What happens if you use Discovery mode to burn a disc? Discovery mode gets it's data from memory (not a real image file) so it'll totally rule out your hdds. The disc it produces will of course be useless to you though!
