OK, i have found a small problem with categories
So far all feeds that i have used have had categories, BUT today i decided to use a feed without, because it is a mixed feed i decided not to lump them all into a single gategory
SO, i left the category box empty, when i imported the feed and looked at the table in phpmyadmin the category box had been populated for that feed, it had been put into category 'batteries'
the only 'mod' i have carried out is the one lised here: http://www.pricetapestry.com/node/175
