Hi Bill
maybe I know why Diki have to discuss about the Blue Ray and DVD quality...

The same happen with my baby girl of 3 years old..
I put one VHS tape carton on TV and she was waching the whole movie without cry and never moved till the end.
Then I have changed and inserted one new Blue Ray disk carton movie..
She waching again the whole movie same as before, she dont understand nothing about the quality..
I think Diki listen and watching music on the same way...

Ah...the only BIG issue that she found on the Blue Ray movie...Dad...SKIP the all Intros and advertisement!!
