Why is it that it seems like you can put any commercial DVD movie into essentially any standalone player and almost always has no problem playing the disk yet there are so many compatibility issues with movies written on blank dvd media? (nice run-on eh?) What brand or type do these commercial companies use? Can we buy that brand of blank media? It sure seems like that would solve a ton of problems. Are there blank dvd's that much better or do they write the data on them that much better; I don't understand the diffence and can't why it's so hard to mimic. Any enlightenment would be much appreciated!
