<div>i can watch Cable when i do a </div>
<div> </div>
<div>"dd if=/dev/video0 of=/dev/video16 bs=64k"</div>
<div>followed by</div>
<div>"ivtvfbctl /dev/fb1 -noglobalalpha -localalpha"</div>
<div> </div>
<div>i guess this means that the ivtv drivers are working fine.</div>
<div> </div>
<div>but i still cant watch live TV. i get a blank screen, and then it returns to the frontend.</div>
<div>where can i find the logs, for "watch Live Tv". </div>
<div> </div>
<div>i have checked the /var/log/mythtv/mythbackend.log, but i dont find any info there.</div>
<div> </div>
<div>any reasons why i must be getting a blank screen ?</div>
<div> </div>
<div>i am using Knoppmyth, R5A15.1, does this version have any problem.</div>
<div>should i try R5A16 ?</div>
