I (used to?) have some old VCDs (or just computer CDs?) that had some (all?) of these episodes. They came in cardboard sleeves like Wii Sports. If I can find them, I'll have to check and see if there are any differences. I was always planning to buy that 14 disc or whatever Superman set but never got around to it.

So, davextreme, how hard would it be to, or can you, make this back into DVDs?

I don't have an ipod/ ipad/ iphone (or any smart phone or tablet) and I hate watching things on PC. How would the quality be if the M4V's were converted back to MPG/ VOB?
