Hi, I installed mythtv 0.19-3 from http://deb.thehunter.ws/. This is "revision 9306 of the release-0-19-fixes branch". Changing channels is fast (less then a second, sometimes a bit more). Also, live tv is working like it should be: smooth when a new program starts and the ringbuffer changes. WAF is waaaay up ;) Stef
