Any update on this? Is there anything I can do in the interm? It's
getting really annoying not being able to use my main TV with MythTV :)
You mention that you can't find the fault with some 10.3 constructed
packages - where do I obtain them, as I can't compile MythTV?
Thank you very much for your help again.
