top reports 53% CPU usage, with spikes up to 59%. Load average is around 2.15. So, 'A'vailable means that the data has been sent from the backend, and the frontend just needs to "decode" it? So, messing with the backend/frontend buffering is not going to help... Since my CPU usage is only 60%, I tried renicing mythfrontend to -3, and X to -4. That *may* have help a little bit, but not much. Oh well, not that big of a deal. I doubt I will use a timestretch > 1.2 very often, but I figured that I should be able to make it work.
