mux/asf.c new --sout-asf-packet-size  switch.  It defaults to 4096, current VLC design, but note that MS' documentation (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmform95/htm/iwmpacketsizesetmaxpacketsize.asp) has: "By default, the maximum packet size is 1400 bytes (chosen because it is below the 1500-byte Ethernet maximum transition unit (MTU) plus the generic routing encapsulation (GRE) tunneling header size)."
