That filename would work, no problem. But the strange thing in the DSPlayer log I posted (the last one) is that, although I was testing with cache disabled, the errors seem to come from cache stuff. See lines 658, 659, 860, 864, 865 and 866.

Can't see the log right now "502 Bad Gateway". Will try again later.

Were you testing with a file you had already cached previously? Because if the file is already cached, if you turn off cache, it will default to playing back the cached on. You can see what it is playing back by turning on force quality prompt, as it will show you a list of all media candidates (offline, original and transcoded). The most top one is the one played during default (with force quality prompt disabled).
