Slow download speeds when using pick your audio + video

[beanman109]

It appears download speeds are affected when downloading any video using the pick your audio + video selection. When downloading using quick download options I can max out my bandwidth, however if I download anything using the pick your audio + video I can't seem to get above 1 mbps.

I've tested this on a server located in the same country as me as well as one located quite far geographically, both seem to have the same issue with the pick your audio + video downloads, I have tested with both SSL & non SSL connections as well as most combinations of video & audio formats. Let me if you'd like a link to some of the instances I'm using to see if you can reproduce this for troubleshooting.
