I recently upgraded to R5E50 and everything went well. On the frontend, I upgraded to Ubuntu Edgy and their frontend build, as it's my desktop system. Before upgrading, closed captioning worked fine. Now, it works fine on the backend, but the frontend sees no captions, even on live tv. Hitting T just says "No captions". Any thoughts on why that would be or what I can do to fix it? I haven't found anything that would prevent just the frontend from seeing the CC.
