Short answer: yes, I'm seeing high CPU usage.<br><br>Long answer: I'm not certain .20 is to blame. I noticed considerably reduced performance after switching from a Knoppmyth to FC 5 install on a AMD 64 3500+. nVidia FX 5200, pcHDTV hd3000, 1 gig ram machine. The last time I used the Knoppmyth setup was to watch the finals of the US Open Tennis with OTA High Def. It worked beautifully.
<br><br>Since then I when to FC 5 / MythTV .20 and have trouble bringing in regular SD with out stutter and freeze. CPU is commonly above 85%.<br><br><br><div><span class="gmail_quote">On 9/12/06, <b class="gmail_sendername">

Back Story:<br><br>I had the machine in a generic tower case, until the wife told me to get<br>a Silverstone case we saw at Fry's (I was going to repaint and modify an<br>old gateway desktop case originally, but hey, I'm not going to argue
<br>with her when she tells me to buy new kit).<br><br>When I moved the hardware over to the LC17, I found that the case didn't<br>leave much room for cables. I managed to cram them all in, but the IDE<br>ribbon is not very smooth and the power wires run in the same area. I'm
<br>not happy about this and I've not had a chance to reroute everything.<br><br>I was using a celeron 2 gig CPU at the time.<br><br>At this time, the digital signal for KPTV (121 in the Portland Oregon<br>metro area) started receiving "WriteAudio: buffer underrun"... a lot of
<br>them, making livetv and recordings from that channel unwatchable (I<br>didn't have any previous recordings, pre-move case change, to compare it<br>to).<br><br>So, I picked up the newer Pentium 4. KPTV started playing back
<br>normally, and the system as a whole started running much smoother<br>(imagine that).<br><br>Enter Myth .20<br><br><br>Pulling the code from the release-0-20-fixes (rev 11157), I compiled and<br>installed. While the system as a whole has some great improvements and
<br>additions, KPTV started getting the audio underruns again.<br><br>During my experimentation with this, I tried turning off deinterlacing,<br>and the underruns were reduced by a noticeable amount. And since<br>deinterlacing takes CPU, it would seem that the .20 rev needs more CPU.
<br><br>Also, the themes seem to be missing menus (going into the brows view for<br>mythvideo using GNAT crashed X as before), but that's something I can<br>fix later.<br><br>So, those of you who are running .20, are you noticing higher load and
<br>CPU usage, or am I running into another issue and just don't know it?<br>_______________________________________________<br>mythtv-users mailing list<br><a href="mailto:mythtv-users@mythtv.org" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
