<br>I believe you add a deinterlacing filter which produces double the frame-rate. I am using Bob 2x. You find it under Setup/Something/Playback, first screen.<br><br>/D<br><br><div class="gmail_quote">On Dec 25, 2007 11:06 AM, Rajesh Kumar Mallah <

I am running mythtv outputting to SDTV via composite TvOut<br>from Nvidia 6200 TC. XvMC disabled. The problem is that<br>while watching LiveTV via mythtv 0.20.2 scrolling text does<br>not scroll as smoothly as in tvtime with all other parameters
<br>remaining same. I found that tvtime is outputting 50 fps from<br>its information menu and mythtv is outputting 25 fps by<br>seeing the logs using -v playback. Does anyone knows if<br>its possible to increase the playback speed somehow in mythtv
<br>to have a smoother playback of scrolling text and images.<br><br>Below is the attached log of mythtv<br><br>thanks for any answers<br><br>regds<br>mallah,<br><br><br>2007-12-22 08:10:15.167 Using runtime prefix = /usr/local/mythtv
