I know ripping DVD's might be a gray area, but seeing as even Sony prdouce software for this (the bloody hypocrite's that they are) i guess it's an ok subject.
I just used CloneDVD Mobile to rip a DVD and played it on my PSP (I ripped with the highest quality setting i could). TBH, I'm not massively impressed with the quality, although its fairly good. What should the quality be like compared to proper UMD's?
Does anyone have any tips for this? Such as, what's the best format to use, best software etc?
