Check your "bad" MCC004 discs. I suspect you may have gotten a hold of the newer discs that start with PAP6 serial numbers instead of the older high quality PAPA serial number discs. Unfortunately, theres no way to tell before you buy. Purchasing Verbatim DVD+R's is a risky move right now.
To find out for sure, look at the clear center of the disc and check out the serial number. If it starts PAP6, you have discs that are known to be lower quality and at least have some bad batches. If it starts PAPA then your OK, those are the traditional Verbatim discs and should be high quality.
In my personal opinion based on my own experiences, the PAP6 discs are junk with about a 25% burn failure rate and an additional 25% of burns ending up resulting in an unplayable disc (PIE/PIF errors) - others have reported better luck with the PAP6 spindles, so if nothing else we can say its a mixed bag of results.

Hope this helps!
