This all seems very incredible to me. If the video data is good enough to be read and displayed on screen, how is it not good enough to be read and transferred to disc? I think it's a safe assumption computer DVD-ROMs are as capable readers as standalones. Is there a way the data can be copied through disc playback? It seems like this would be a handy piece of software that makes like it's playing back the disc whilst copying it. On that note, I think I'll try a 1.0X rip.
Also, ISOBuster provided me with no better results.
