*.vc1, IIRC? Although I rarely used it for much.

Yeah, VC-1 AP had a standard elementary stream format, though I can't remember if that was defined in SMPTE 421M or in some other standard. But it definitely did exist.
VC-1 SP and MP, because they originated as WMV9 codecs, were indeed tied to ASF container so they never had an officially standardized ES format. However, there did exist an unofficial one used internally at Microsoft. I only knew it by its extension, RCV, but I honestly have no idea what it stood for. I distinctly remember using an ASF2RCV command line tool.
Ben, what do you think is the statute of limitations on our Microsoft NDAs?
