[mythtv-users] Very Slow EPG - Need to restore (or delete) all channel icons

[Noel Murphy]

Maybe I'll just download this icons myself. I have about 80 though so  
it is going to be a pain. :(

I actually have done the EPG tip from Jarod's site.
The perl script does create all the .url files in the /tmp folder and  
the iconmap.xml file, but the mythfilldatabase line does pretty much  
nothing. Exits in under 10 seconds. I've run it as mythuser and as  
root. It never causes the images to get downloaded, even though if I  
grab a url from any of the tmp files and put it in my browser, it  
works fine.

I don't think it is even attempting to download the images.
