When using source, default:'medium' not working properly

[tylik1]

i have 6 sources sorted by quality. 2 low, 2 medium, and 2 high. Manually changing works fine, but default only works with high and low quality options. Medium is not working. Although there is a workaround with player.ready and currentResolution() method

I recommend setting the res tag or value and using that to select your quality

Setting the res value and then using that to select quality is what I had to do to get around a similar issue also.
