Yea, I made a backup copy of Holiday last week with my 241040a Plex, I wanted to try CCD4, I heard it does help our Plex models to copy these discs with SD 2.51. As you are probably aware, the Plex has had problems with SD 2.51, as I was unable to backup MOHAA with my Plex using CCD3, I still have to try that one yet. I am using FW 1.03, and made a copy to a memorex “high speed” re-writable disc. I used the default settings in CCD4 for game copying.
There is a lot of information about the Plex, and its’ ability to copy SD 2.51+, not a lot of it is encouraging. But for me, CCD4 has made a difference, but I still need to try MOHAA to verify complete success.
Perhaps it is your using FW 1.04?
