<div>James,</div>

<div>Let me guess, you're recording DVB (e.g. DVB-T/Freeview) streams right?</div>
<div> </div>
<div>If so then I encountered the same problem, it turned out to be when the DVB stream contained more than one audio stream the playback would stutter terribly.</div>
<div> </div>
<div>I created a quick and dirty fix for mine that records only the first audio stream I find (for the channel). Although logically this might encounter problems (I should really look for the first stereo audio stream), in practice I've encountered no problems....
