Well, it's a server-side problem, so there's nothing I can do on my part. A general observation of mine is that VODs on both mp4.48.cn (I actually haven't seen mp5.48.cn much myself, but it's probably safe to assume it's hosted on the same infrastructure) and ts.snh48.com rot over time, so you do need to act fast, and some old VODs are probably lost forever unless you can find someone who has kept them.
