One solution that immediate comes to mind is that the major software vendors should be encouraged to 
certify hardware that is proven to work with their software.

George, do you think the problems you documented come about from editing program - hardware driver 
interaction or is it more often than not purely editing software simply mangling data?

And this also raises the question, for the small/budget-starved institution, maybe it IS a better 
idea for them to record directly to CD media, on the assumption that a dedicated CD recorder used 
with good-grade media is less likely to mangle its own data?
