Very slow ripping

I have also had the same problem. My drive was only ripping at 1.0x! I
tried _all_ of the methods posted in this forum to get the speed up, but
was only able to increase it to 2.0x. I have a thought on why this may
be, hopefully someone can help guide me...
Here's my situation: I have a CD-RW/DVD drive that reads at 52x (52x
CD-R, 32x CD-RW, 16x DVD...if relevent). I've tried using this drive
in Windows and it rips very quickly, though I cannot recall at what
speed. As I mentioned above, I have tried all methods mentioned
previously in this forum: SCSI emulation, turn off CD/DVD auto start,
turn on DMA, etc. Out of curiosity, I looked at my
/proc/sys/dev/cdrom/info file, as the original poster did, and it
showed the following (before SCSI emulation):
CD-ROM information, Id: cdrom.c 3.20 2003/12/17
drive name: hdd
drive speed: 4
drive # of slots: 1
Can close tray: 1
Can open tray: 1
Can lock tray: 1
Can change speed: 1
Can select disk: 0
Can read multisession: 1
Can read MCN: 1
Reports media changed: 1
Can play audio: 1
Can write CD-R: 1
Can write CD-RW: 1
Can read DVD: 1
Can write DVD-R: 0
Can write DVD-RAM: 0
Can read MRW: 1
Can write MRW: 1
Can write RAM: 1
As you can see, it shows drive speed at 4! Why is that? Well, I
thought that may be the problem. After I performed the SCSI emulation,
I looked in the file again and found the following:
CD-ROM information, Id: cdrom.c 3.20 2003/12/17
drive name: sr0
drive speed: 52
drive # of slots: 1
Can close tray: 1
Can open tray: 1
Can lock tray: 1
Can change speed: 1
Can select disk: 0
Can read multisession: 1
Can read MCN: 1
Reports media changed: 1
Can play audio: 1
Can write CD-R: 1
Can write CD-RW: 1
Can read DVD: 1
Can write DVD-R: 0
Can write DVD-RAM: 0
Can read MRW: 1
Can write MRW: 1
Can write RAM: 1
Now the speed's changed to 52, as it should be! Yet, I'm still ripping
at 2.0x. So what's going on here? What am I missing? Anything else I
can try? ](*,)
Thanks!
P.S. Why did I have to do the SCSI emulation to get the speed up to
52, as what it should be? Are there other methods? I'm not sure if
this should be saved for another forum thread, but I was just curious
since I don't understand this whole SCSI emulation thing.
