hi Ethan,

The was another combined thread on this issue last November:  
[V10 - MrSidRasterLayer & Jpeg2000RasterLayer - Exceptions](https://community.thinkgeo.com/t/v10-mrsidrasterlayer-jpeg2000rasterlayer-exceptions/8696/20)

In that thread we were able to get MrSid and JPEG2000 working.

Dennis
