Hi Mike
I have used the Kramer XVGA to Cat5 devices at UofW over standard Cat6.
I have experienced no problems, and I am very happy. I plan on using 
more of them in the future, in our classrooms.

Call Sherwood Audio and talk with them about the Kramer devices, they 
were helpful in making my decision.
