In the SMP7 database, filters are still named collections. You might want to check my joins on this one, but if you know the name of the filter you want to use, run this sql query and then you can copy the list out. It's not as simple at the 6.x days, but at least it gets the data out for you.
In my example below, I'm using the filter 'All Windows Computers' which you would substitute for the filter of your choosing.
SELECT vComputer.Guid, vComputer.Name, vCollection.Name AS Expr1, CollectionMembership.ResourceGuid,
vCollection.Description
FROM CollectionMembership INNER JOIN
vComputer ON CollectionMembership.ResourceGuid = vComputer.Guid INNER JOIN
vCollection INNER JOIN
Collection ON vCollection.Guid = Collection.Guid ON CollectionMembership.CollectionGuid = Collection.Guid
where vCollection.Name = 'All Windows Computers'
