Description
when viewing tickers (such as news and sports tickers) at various timestretch settings, the results can be jerky.
this seems to be due to avsync matching the wrong rate.
may be similar problem to #5643
patch attached.

using opengl vsync with no acceleration, audio controls timing.
xvideo, standard and linearblend/kernel deint on one. xvideo, standard and greedyx1/yadifx1 on FE.
1080i and 720i dvb source. display is 60Hz in both cases (TV's). original src material is 50Hz (aus DVB). various timestretch speedups between 1.0 and 1.85.
ive been running this for a couple of years. gave it to a few people for eval. simon kenyon most recently. said it was much better.
most noticable in motor racing and news tickers. havent tried without for a long time. effect was 0.5 secs normal and then 0.5 secs hurry up for video out rate adaption. I suspect rtc is why you dont notice it.

Follow up moved to mythtv-dev.
Mark, I tried your patch, but didn't see any significant difference. If anything, your patch might have made things ever so slightly more jerky. What content and configuration are you using? I used 1080i content, VDPAU temporal 1x deinterlacing and RTC frame timing for my testing.
