DVD Shrink and DVD Decrypter

Can anyone tell me why after I burn using DVD shrink with DVD Decrypter it play great on my computer but I put it in my DVD machine it plays all funny.

 

What type of media are you using?

 

AND what speed did you burn at?

 

Here is my observation.
1. If DVD plays on a computer, then it will play on a NEWER DVD player, but may NOT play on an older DVD player.
2. A few people told me that DVD-R is around longer than DVD+R, so DVD-R is likely more compatible with older DVD players. However, I used more DVD+R in the past than DVD-R and they all played well on my older DVD player, personally it is hard to believe.
3. I think it is a software problem, but they are all created by the same softwares. It is a mystery to me.
M.K.

 

I just would like to thank everyone in aswering my question. my DVD is old and had to be changed now all my burns work very good on my new machine. Again thank you for all your help.
