Yes DMA is enable ... I was getting writes of about 50m/sec when I tested. I'll disable OpenGL and recompile with some optimizations. I'm running Kubuntu ... Any thoughts on where to find optimizations ?
Thanks for the help ...

For the backend, dumb question - is dma enabled on the disk(s)? For the frontend, I had to recompile with processor specific optimizations before I got reasonable CPU usage. YMMV. -Jerry _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
