Dear Bill and MMC WG members,
I have the information regarding "MRW Validation Suite" to you.
This software is using Function31h(Read DVD Structure).
MRW Validation Suite does not do an action if the device does not support this Command.
Accordingly, I changed the design of the our device.
( The repetition of trial and error. )
MRW Validation Suite wished that receives the 4Bytes header and RAW-MTA data from the device.
When it eliminates these specification from the device MRW Validation Suite stops the test.
I think, that you should discuss as the Philips regarding this problem.
Dr.Paul.weijenbergh, Mr.Jaap.Nijboer, Mr.Peter Bentvelsen etc..
