Yes OP had trouble downloading the file without extension.
I just took the "freedom" to broaden the topic a bit.
Riamus thanks for that explanation. I admit I didnt do my homework by searcing the forum before posing.
I just assumed that /splay will use "right" codec if i specify one of -wmp switches. And thus thought it can't play the sound due the missing file-extension (ie. cant access the file)
