not have video/audio synchronization problem?<br>><br><br>Actually, recording LiveTV can't be disabled (and would prevent you from <br>pausing, rewinding, or fast-forwarding as you watch, anyway). However, <br>recording LiveTV shouldn't be causing issues with a machine of the specs <br>you've provided ( <br>http://www.gossamer-threads.com/lists/mythtv/dev/214074#214074 ) /if/ <br>we're talking about standard definition (i.e. NTSC or PAL). (Your CPU <br>is right on the edge of being able to play back high-definition content <br>without help, but that would likely cause other problems--not just A/V <br>sync issues.)<br><br>Usually when there's an issue with video lagging behind audio, it <br>indicates that you're listening to the audio from the capture card <br>instead of the audio from the encoded video file that you're playing <br>back.
