Many thanks for that - I'm learning all the time

From your link, I found out how to filter the search on bitrates after the search results come in, but I couldn't get your tip above to work for filtering the results before they arrive on the pc ? ? When I tried what you suggested above, I keyed in 256 in the bitrate section, then about 25 tracks were in the results, but no track lengths ! !

Also, and on the assumption that I can get eventually get it to work and you only wanted to view the results based only on br's of 256 and 320, how would you input that into the box please ?
