I was expecting that question, but I don't have a good answer. You can try using ionice or renice to change the priority given to myth-backend, but they won't provide a nice linear speed control. To do that, you'd need to do something like writing a small program that can feed a video stream into one end of a named pipe at a variable rate, and have myth-backend read from the other end. (I seem to recall that MythTV supports a tuner type that reads from a file or a device, which you might be able to point at the pipe.) Obviously not a trivial setup, but ionice might do the job adequately. >>> I've wondered if it has a correlation to the "Control TCP Receive >>> Buffer" and "Program TCP Receive Buffer" settings... > > So what are good settings?

Looks like I've been using 4096 for "Control TCP Receive Buffer" (probably the default), and 43,689 for the "Program TCP Receive Buffer" (probably boosted years ago when I first encountered problems). A bit of browsing in the source should turn up the actual defaults (or just boot without a settings file). -Tom ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _______________________________________________ Mvpmc-users mailing list Mvpmc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mvpmc-users mvpmc wiki: http://mvpmc.wikispaces.com/
