[mythtv-users] Smoothing out the channel change script

Thanks for the response.
After I started examining my processor speed I realized that it was only
being detected as a 1GHz when it should have been detected at around
2.4GHz since its an Athlon 64 3400+
I turned off the cpuspeed service which caused fedora to detect it at
2.4GHz however I still wondered why the kernel had been seeing a 1GHz
CPU so I checked my BIOS settings.
I turned off the "AMD Cool & Quit" setting in my BIOS and
restarted...bingo my CPU was detected at 2405.514MHz even while the
cpuspeed service was running.
So I fixed that problem however, my channel change script still stutters
like before :-(
I tried nicing the irsend commands in my script with no luck.
Is it possible that its one of my recording settings in myth.
I notice right after the stutter it comes up with a position saved
before the channel actually starts to change.
Any help would be great.
