[G4] DVD Media

[GDB-MDD-X.4.6]

While transferring my VHS tape collection to DVD, I ran out of the  
Ridata DVD-R media I was using found a 100 pack of Imation DVD-R at  
Walmart for a decent price, so I picked those up to finish the task.   
Bad decision.  Out of the 50 pack of Ridata I had no bad ones at  
all.  Since switching to Imation 6 out of 10 so far have been bad.   
Anyone else having problems with this brand?

Just a message from Doug...
