</div>Thanks for the help. I'm using the blaster found at the link below.<br>

I thought I was having an over saturating issue but it also happens on<br>
startup. By startup, if the TV hasn't been on and I start watching<br>
LiveTV naturally it'll blast the last channel I watched. Even on<br>
startup sometimes I see the issue so this rules out over saturating<br>
issue.<br>
<br>
I wrote a simple script just to repeat/loop the irsend command and I<br>
moved the blaster around to find the optimal location. I then stuck it<br>
on with painters tape and then covered this with electrical tape. I<br>
figured this would avoid any reflections and interference from<br>
fluorescent lights.<br>
<br>
I'm going to try the min_repeat.<br></blockquote><div> </div></div>I'm using that same blaster and having the same problems you are. It worked perfectly under ubuntu 8.04 but started failing every so often when I upgraded to ubuntu 9.10. No amount of electrical tape/delay adding/nicing seemed to help either :) My guess is that something in kernel-land changed timing wise.<br>
<br>I ultimately gave in to the lists' conventional wisdom and bought a usb mce transceiver because everybody says it "just works". Unfortunately I got a gen1 device which now can blast anything that isn't 56 kHz so I was out of luck there with my 56 kHz Scientific Atlanta box. <br>
<br>I read a couple of weeks or so ago on this list that someone else with this problem switched to using Jarod's git tree and things went back to perfect again so I figured I'd give that a try. But his current git tree wouldn't build against the kernel source that the ubuntu 9.10 packages provide. I can probably make it work but my first attempts failed with:<br>
<br>/bin/sh: cannot create /home/me/jarods_lirc/include/asm/asm-offsets.h: Directory nonexistent<br>make[1]: *** [/home/me/jarods_lirc/include/asm/asm-offsets.h] Error 2<br>make: *** [_module_/home/me/jarods_lirc] Error 2<br>
<br>I'm sure it's something stupid on my part, though.<br><br>At this point I've come to 2 conclusions:<br>1) LIRC hates me. Passionately.<br>2) Meh, it's almost summer time :)<br><br>Here's the thread where Jarod's git tree is reported to work better than lirc cvs for modern kernels:<br>
