I am not trying to say that the LiteON LDW-411s cannot burn Ritek DVD-Rs, but I *AM* trying to say that I have had mixed results. Ritek DVD+Rs have performed much better in my drive.
RJW: Too late, I bought it already!

and yes, it is the newer version that officially supports both formats... we shall see though! It'll take me a while to be able to afford a mod chip though... the place I have it done wants to charge $150 CDN to do it... and after shelling out ~$300 already for the unit, 1 game, and a memory card... I just can't justify it yet. I can still test DVD-R and DVD+R movie backups though.
bichi: K-Probe is not so much misleading, as just not reporting all the neccessary information required to make a good judgement of the media's quality. Also, how did you set K-Probe 1.1.26 to SUM 8?
