When I extract MPG files from a VCD with either Lite-on LDW-811S (a DVD writer) or Lite-on XJ-166S (a DVD-ROM drive), the extraction speed is very fast, just as expected. But if I run two copies of ISOBuster at the same time to extract from two VCD's, one in each drive, the extraction speed of one of the drives would be about 1/6th of the full speed. The DVD writer is connected to the primary IDE channel as the master, and the DVD-ROM drive to the secondary IDE channel as the master. There is no slave device. My only harddrive is a Serial ATA drive, which is connected to the SATA port. Extraction speed is not limited by the transfer rate of the harddrive, since the sustained write speed of the harddrive is more than 25MB/s. I used the default setting of ISOBuster.
Is there some setting in ISOBuster that would allow me to run two copies of the program and extract at full speed from 2 VCD's at the same time?
Thanks for your help in advance.
