Since I have been using Webgrab, I used the "suggested" default setting :
<retry time-out="5" channel-delay="5" index-delay="1" show-delay="1">4</retry> show-delay="2">
tried to change on my xml that grabs different sites, but I could not find an optimal setup, Actually I found it looks faster without any settings, but on some site does not grab epg. What is your advice / best setup ?
