Poor Quality Blu-ray discs

[colnscott]

Has anyone bought a Blu-Ray disc only to find the quality of the picture is not much better than the DVD release ?

For example, "Stargate", "Independance Day"
.
It seems to me that some companies are using DVD source material / transfers rather than pay for a new transfer - This seems to undermine the whole point of the Hi-Def movie experience.
Compare this to a company like "The Criterion Collection" where you know that you will get stunning picture reproduction EVERY time.

Should we be on the look out for poor quality discs and make sure the distribution companies get to hear about this.

I use both Region 1 & 2 discs on my system. When I get what I consider to be a dud I check it against another region release - if both are equally dud quality I send them back.
