Just a small tool for those who have problems using one of the popular replay sites:
http://quickswans.de/replays/
As stated, works for haxballtube, haxrec, shaxball and 0x0c, though it's probably most useful for the latter as it causes trouble on some browsers. (Won't work if the site in question is down, though.)
Let me know if something doesn't work as expected.
