Are EZH disc's a problem?

[mindonstrike]

You say these EZH cdg's have copy protection but not multi-session. What kind of security is it?

I would think that if this is a good quality brand as you report, there would be other EZH/Hoster users having problems with them.
Based on the fact that yours is the only report of a problem with this brand, and I know of no problems with the other brands you mentioned, I'm inclined to think it's a hardware problem as nreel suggested and/or possibly a poor media quality problem

IMHO

P.S. I was going to purchase one of these to check out but they don't seem to be available in the U.S.
