I apologize if I picked the wrong sub-forum to ask this question.
This is a bit of a hypothetical question that came up in a discussion regarding making stand-alone DVD players region free. I also apologize if the question is not clear.
Are the drives in current DVD stand-alone players communicate with the host system over some revision of MMC protocol encapsulated in something?
In other words, are the drives in the 60 dollar throw away Panasonics, etc talk to the system proper using IDE (perhaps over some sort of non-standard connector) or SATA protocol, with standardized MMC commands embedded in it? I am not concerned about connectors, just about the communication protocol between the host system and the drive.
Or are the drives highly specialized, and mutated into doing their own thing, talking host specific protocols?
If I am familiar with, say, MMC 6 spec, and familiar with the way CDBs are encapsualted in USB, (or over IDE, SCSI, whatever), and I take the scope to the data lines of a stand-alone's drive, will I see something familiar, or will the communication protocol be totally different?
Thank you very much.
