// packets will not come back, so the mmsu will failed.
// * Then we can try TCP, but if there is a proxy for
// internet connection, the TCP connection will not get
// through
// * Then we can try HTTP.
//
// Note: MMS/HTTP support is now a "well known" support protocol,
// it has been tested for while, not like MMST support.
// WMP sequence is MMSU then MMST and then HTTP.
// In MPlayer case since HTTP support is more reliable,
// we are doing HTTP first then we try MMST if HTTP fail.
