Aside from an actual pile of steaming poo, Ridata is crap. Splurge a little and get Verbaim DVD+R DL media, burn in the UDF format at 2.4x and it should flawlessly. Also,be sure to have the latest Nero. Memorex media also works well, I have been using that lately with great success even on the 360. Also, I've used Ridata in the past and getting to verify properly is almost impossible because it's only compatible with a few DVD burners. Most burners require special firmwares just for Ridata. I suggest either NEC or Lite-on. Not the most popular but after going through nearly 20 DVD burners over the past 5 years I think I know a thing or two about burners and those brands have the widest compatibility with media.
