My sons want "Back to the Future" (1, 2 and/or 3) on their Nintendo DSi's via DS Two flashcarts. I have original DVD's and also rips sitting on my home server. Only problem is, Mummy doesn't like the frequent casual profanity. So I proposed to "bleep" out the offending bits and edit the ripped movies.
Although I have vague ideas on what to do, I could use some help in general approach and also specific software tools that, preferably, would be free or cheap and specifically geared to this kind of operation. Thanks!
