Hi Jan,

You could be right it's a long while since I compared them, things may 
have changed.

When I enquired why there was such a big difference in speed I was told 
it was because the sqlite version only pulls in new and updated programs 
when it updates whereas the other did a full update each time. I don't 
have very fast internet which probably had a big effect here.

So the first update is slow until it populates the DB but subsequent 
updates are much faster.

I don't remember the details but you can tailor the lineup through the 
xmltv command line interface to the grabber.

I hope this email makes it to the list quicker than my last email it 
took about 5 or 6 hours last time!
