A few questions:
1. which of the two Pioneer 112 S-Drives on your mac are you using to burn with?
2. have you tried burning to Verbatim dvd-r on BOTH S-drives? and if so, did you get the same results on both burners?
3. are you using the latest firmware? (if not, you'll need to update now before going any further). run apple's software updater if you haven't already.
4. Did you install the 2nd S-Drive yourself? or was it professionally installed for you?
5. Are both S-Drives on the very same bus? And if so, have you tried a test burn on the
stock drive without the second drive attached? (simply disconnect the second drive from the bus while your mac is powered off /shut down and then power back up). Make certain you are grounded to avoid electric /static discharge / It's a good idea use a grounding strap when disconnecting the second drive or reconnecting. If you don't have one then simply touch the metal frame to the mac prior to working on it.
6. Have you been able to make a disc image to the desktop, and then burn from that image to Verbatim Dvd-R at 4x or slower?
7. Did you remember to select which drive you want to burn from within iDvd prior to burning a dvd?
