Anyway, I think I now know how to add the needed new functionality on to the old bufferring. If I can just find time to try it...

Here's a small patch that might help. It's not in the official code because it can cause other problems, mainly sluggishness in other areas, if your system isn't fast enough. Thanks. I actually use packages and do not compile myself, so I will wait for this to be incorporated into a version of myth and deal with the slow skip issue till then. I also have a slow machine so I do not want to introduce other problems. Just out of curiousity, why did the skip ahead/back become slow with .17? -- Email me if you want a gmail account, I have invites. ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

I have some other ideas to try to improve skips and speed changes, but
don't know when I will get to them. My plate of things to do seems to
always be full.
