So, if you specify V.UserID = 1 it does not work, and if you don't specify it, it works but it's slow, then you do not want to be specify this clause. What you do want to be looking for is the reason for this poor performance. You to be doing an EXPLAIN on this query, seeing if you can maybe add index(es) to improve performance. You show the 'structure' of the tables but not what indexes you currently have. Post the results of the EXPLAIN for the query and also SHOW CREATE TABLE for each table.
