The lower the queue, the faster it can be filled (=less delay on seeking, especially with "delay playback until queue full" option), but if your PC lacks processing power, you will get dropped frames once it hits a demanding place.
So to find out if your queue needs adjusting, play a video of your choice and look at queue numbers on the OSD. If you get dropped frames and any queue shows as empty (or dangerously low), try increasing it by a few steps. I imagine the default values are sufficient in the majority of scenarios.
So far I only saw ONE video with .ass subtitles that dropped frames on default settings (the same I had to increase my cpu queue to 64 for). Even those subs that used to be regarded as "very heavy" with VSFilter (not Xy-VSFilter) decode without problems on my machine on default settings.
