Paul, I'm dealing with large amounts of Mastermap data too. You can only import the files one-by-one using the converter supplied in MapInfo 7.5. You could be a masochist and do this and then create a seamless layer, but then you can't process a seamless layer table! I would be interested in anyone who may have written a MapBasic program to automate this.
I tried MapGML (see http://www.mapsbydesign.co.uk/mastermap.html) This works well and can converts straight from the .gz files. You can change the convertion script to split the layers how you want. There is a demo version available on the site. Ordnance Survey recommend MapGML for MapInfo... http://www.ordnancesurvey.co.uk/oswebsite/products/osmastermap/systems/ Keep me updated with what you find & I'll do likewise.

I have requested the GML data from OS but this has been supplied in 5km by 5km 'chunks' (or tiles). In the past I have only imported individual GML files to Tab by using the 'Table > Import...' option, but now I have 75 GML 'chunk' files which need merging into 1 Tab file (ideally without causing overlaps/duplication). Does anyone know how MapInfo deals with multiple GML 'chunk' files?
