So, the DVDs I burn only play on my computer and ps3, not my DVD player. Maybe its because theyre Divx but even the WMV ones dont play on there. Also, I can only burn movies that show up in my Windows Media Player Library and not all movies do even though they seem to be the same format. Last and least why cant I rip the movies back off of the dvd's because I just bought a external hardrvie and would like to back up my movies.
