I have just started using the newest version of the SDK and with great joy found the new ReadLB() function. Upon using it in my code however, I have found that code which used to take 3 minutes to rip an entire CD now takes 5 minutes to rip one track. Am I doing something wrong? This code originally used AK-Rip, so I know I'm not up against some kind of hardware issue. Here's the basic layout of my code:

result = StarBurn_CdvdBurnerGrabber_CreateEx(&m_hDrive, textresult, sizeof(textresult), &sysresult, &cdbinfo, (PCALLBACK) StarBurnCallback, this, m_DeviceName, 1);

result = StarBurn_CdvdBurnerGrabber_SetSpeeds(m_hDrive, textresult, sizeof(textresult), &sysresult, &cdbinfo, CDVD_SPEED_IS_KBPS_MAXIMUM, CDVD_SPEED_IS_KBPS_MAXIMUM);
StarBurn_SetFastReadTOC(TRUE);

unsigned char buffer[2352];
for(i=0; i<TrackLengthLB; i++)
{
result = StarBurn_CdvdBurnerGrabber_ReadLB(m_hDrive, textresult, sizeof(textresult), &sysresult, &cdbinfo, TrackStartLB + i, buffer, 2352);
/* Write the samples to disk */
}

StarBurn_Destroy(&m_hDrive);

PS: This code had been using StarBurn_CdvdBurnerGrabber_GrabTrack() in the last version of the SDK, with the rest of the code unchanged.

You have to read with multiple sectors to get acceptable speed. Reading with one logical block per request is always very slow. Fix your code :)

Yes, naturally, but there doesn't seem to be any function for doing that?

Stupid me! Please drop me a message and I'd issue you with updated version of the StarBurn with block read enabled. Also it has fixed the issue with DVD-ROM recognition you've mentioned in the other thread. Thanks!

Okay, I have the latest DLL in place and the new ReadRaw() function is allowing me to read much faster, thanks!
