<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'm pretty new to linux and mythtv so bare with
me.</FONT></DIV>
<DIV><FONT face=Arial size=2>The last couple of weeks I've been setting up a
mythtv combined frontend/backend system on a 2.66 Core 2 Dual system running 2Gb
memory, 2x500Gb SATA HDDs, 1xNvidia 7600GS, 2x TechnoTrend 1500 DVB-C tuners.
I'm running ubuntu 7.10 dist but with minimal install and have added packages as
I have needed them.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>For the record I have some, relatively
minor problems like pink screen of death, pixelization while watching
normal tv and stuttering while watching hdtv but o</FONT><FONT
face=Arial size=2>ne of my more serious problems, the one which I would
appreciate some help with is that when I'm recording on one of my tuners
and watching live tv on the other tuner, the program I'm watching will
freeze after about 20 sec leaving lots of "NVP: Prebuffer wait timed out 10
times." in the mythfrontend.log. I don't know </FONT><FONT face=Arial
size=2>what this messages means. Then after about 20-40 sec the picture
starts running again and runs for about another 20 sec then hangs and so on
and on. </FONT>The recorded show seems to work fine without any interference.
<FONT face=Arial size=2>This unfortunately makes my dual tuner setup pretty
worthless for me :(</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I can't see that it could be a performance issue
with my hardware so I guess that I probably have a faulty setup or something
wrong with some hardware. According to the fairly even intervals of the error
and the events written in the frontend log I would guess on perhaps some
kind of memory buffer trouble?</FONT></DIV>
<DIV><FONT face=Arial size=2>I have noticed that all my memory seem to be
drained by something, leaving about 50 megs of a total of 2000 free. Don't
know if this is normal behavious on a fe/be system.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any advice, help or suggestions on pointing me in
the right direction would be very welcome.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thank you</FONT></DIV>
