I am one  of those who tested Josh's patch/replacement libmythavformat 
file.    The difference on my 18722 mythbuntu 8.10 installation was 
quite remarkable.   Just as a test,  I put the original libmythavformat 
file back.   The  "IR Remote button press" delay was immediately 
apparent and irritating.   With Josh's file,  it's literally  gone. (I 
did make the other two changes  (xorg.conf and no screensaver) but the 
immediate and big improvement came with the installation of Josh's 
file.  I'm now even running with playback profile cpu++.  Using that 
profile,  and old the original file, my mythtv installation was 
crippled.  Earlier, I suggested using "high quality" which seemed to 
reduce the severity of the problem  but with Josh's file,  changing to 
"high quality" isn't necessary.  The mythtv developers certainly need to 
incorporate Josh's proposed changes,  IMYHO.  Kudos to Josh for 
identifying this!

 If anyone else tests Josh's fix file,  please post your results here 
under this thread.   If more find the fix to be helpful,  then maybe we 
can drop a reference to this thread in the developers list.   The test 
is completely reversible.  I used a  "sudo cp " to make a duplicate of 
the original file, titled  libmythavformat*.orginal and then sudo 
cp"ied  Josh's fix file into /usr/lib overwriting the original.

Very roughly, these are steps I followed to install and test Josh's fix 
file on my Mythbuntu 18722 8.10 installation:
1.  sudo /etc/init.d/mythtv-frontend stop
2.   sudo /etc/init.d/mythtv-backend stop
3.   mkdir ~/Desktop/temp
4.   Detach and save Josh's  attached .gz into temp
5.   Use  Archive manager to extract  libmythavformat.xxxx into temp.
6.  Make a copy of the exisiting file so you can return to the original 
if necessary for testing or if the fix file causes your mythtv 
installation to balk.
 sudo cp /usr/lib/libmythaformat-0.21.so.0.21.0  
/usr/lib/libmythaformat-0.21.so.0.21.0.original
7.   Copy Josh's file over writing the original (which you just made a 
copy of in step 6)
 sudo cp ~/Desktop/temp/libmythavformat-0.21.so.0.21.0 
/usr/lib/libmythaformat-0.21.so.0.21.0
     If  prompted to overwrite indicate yes.

7.5 sudo chmod +r /usr/lib/libmythaformat-0.21.so.0.21.0
7.6 sudo chown root /usr/lib/libmythaformat-0.21.so.0.21.0
8.  sudo /etc/init.d/mythtv-backend start
9.   then start mythfrontend via the system menu as you would normally
10. Post a summary of test here.  (Thanks)
