Can you say more about the data you have? How are you processing that data?
I also had a situation where "also viewed" performed poorly. The problem was actually that viewing is a very poor indication of engagement. Getting a better indication (viewed for 30 seconds) made a world of difference in the results. No amount of fiddling with the raw view data itself made any difference.
