Depends... AVI: Index is at the end, so it might play fine in a tolerant enough player. MPEG-TS: Headerless. Will play fine in any player. MP4/MOV: Index is sometimes at the end; if so, it might play fine in a tolerant enough player. MKV: Has a header and index, usually at the start. Probably won't play. Ogg: Has a header, but is indexless; might play fine in a tolerant enough player. Probably not though, as both Vorbis and Theora (the only things Ogg supports that are ever used) both rely on custom Huffman tables in the headers.
