I copied the file to a PC and played it on there and got similar results.</div><div class="gmail_extra"><br></div><div class="gmail_extra">I'm using a HD Homerun with DVB-T broadcasts. Recently I also installed a DVB-T PCI card to get more simultaneous recordings. Is the problem more likely to be signal strength or I/O bottleneck? I guess signal strength can be fixed with some sort of boost device, but an I/O bottleneck would mean buying faster disks.</div>

<div class="gmail_extra">2) The TVs in the house don't seem to have signal issues (which is why I now think this may be I/O rather than signal strength, but happy to be told otherwise).</div></div>
