* bFormatIndex - A non-zero constant that uniquely identifies the

* bDataOffset - Offset to TSP packet within MPEG-2 TS transport
* stride, in bytes.
* bPacketLength - Length of TSP packet, in bytes (typically 188).
* bStrideLength - Length of MPEG-2 TS transport stride.
* guidStrideFormat - A Globally Unique Identifier indicating the
* format of the stride data (if any). Set to zeros
* if there is no Stride Data, or if the Stride
* Data is to be ignored by the application.
