TDK is fine, ditch the princo. When you ask a question like this you should tell particulars:
burner, burn speed, firmware, processor, ram, HD etc. so people don't have to ask so many questions. Always use good media, the cheap crap winds up costing twice as much in coasters, not to mention wasted time and aggravation. Try Taioyo Yuden, Verbatim, Maxell, Ricohjpn, TDK for media. Burn at the recommended media speed until you are happy, then you can experiment with faster burns. Check out some of the forums, chances are someone already had your problem and someone helped him out. Good luck.
One other thing, I'm not familiar with the DV-355, some players more than 2 yrs. old have a hard time with +R media. How old is your player and what is your media + or -?
