Well, h.264 is not just used in Blu Ray. There are satellite HD programs and recordings of such. I have some (on UK Freesat), and I have an NV44. In my particular case, I got the NV44 in late 2006 because it had no fan (I wanted a quiet system) and it gave a DVI output to my AGP motherboard. Upgrading that would mean replacing the motherboard (to get PCIx), that means replacing the RAM... and all that to see HD sat? Or should I just forget acceleration and try to tweak the decoder - currently the xine engine in kaffeine - to do HD sat in CPU? It's a 3 GHz P4 so it might do it, especially since the bitrate is not that high and no scaling is required? I could do with 720p if I knew how to decode that from a "full HD" stream. -- Yours, Mikhail Ramendik Unless explicitly stated, all opinions in my mail are my own and do not reflect the views of any organization _______________________________________________ Nouveau mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/nouveau
