I am using VDPAU for playback.<br><br>It seems to be worse with TV1 than TV3 which is a surprise give teh higher resolution of TV3, but on the other hand it seems that TV3 is on stronger transport than TV1.<br><br>I suspect my reception may be the cause of the problem but I am having trouble getting any good information on BER and SNR for the NOVA-T 500 card.<br><br>I run dvbtune -f 690000 -I 0 -qam 64 -gi 16 -cr 3_4 -bw 8 -tm 8<br><br>I get a result that gives signal strength of 34948<br>bit error of 0<br>but SNR also 0<br><br>It seems impossible that SNR would be 0 surely it should be something else. Which causes me to wonder if the BER is really zero.<br><br>I have seen reports of DVB-T reception in this

<br>What application do I run to get a report like the one above? <br><br>I guess if I confirm that BER is low and unc is zero then I can eliminate (or not) reception as being the cause of the artifacts.<br><br><br>Cheers<br><br>Steve<br><br><br></div></div><br>
