Correct.

To add confusion, any given bacula drive can only support one media type.

The only way around this problem is to define extra drives for each 
media type supported (ie, LTO5, LTO4 and (read-only) LTO3).

I don't know how well this solution will work in terms of concurrency, 
I'm about to try it as I've been told to reuse ~200 LTO4 tapes from 
another project.
