    initial v1  
    11Hi reimar & cehoyos. You are right, I got 608 and 708 confused, nonetheless, both CEA-708 and EIA-608 subtitles are present in the file. 
    22 
    3 * NCIS.wtv, Stream 3. Subtitles are stored using EIA-708. By no coindicence, the stream type guid is MEDIASUBTYPE_DTVCCDATA. Most packets in the stream correspond to a CEA-708 DTVCCDATA packet (described in the CEA-708 standard). There are also many 2-byte packets, which seem out of place; perhaps they are frame counters or checksums added by Microsoft. 
     3* NCIS.wtv, Stream 3. Subtitles are stored using CEA-708. By no coindicence, the stream type guid is MEDIASUBTYPE_DTVCCDATA. Most packets in the stream correspond to a CEA-708 DTVCCDATA packet (described in the CEA-708 standard). There are also many 2-byte packets, which seem out of place; perhaps they are frame counters or checksums added by Microsoft.

    55* NCIS.wtv, Stream 1. If you copy this stream into TS format, the CCextractor program will extract subtitles from it. The subtitles within Stream 1 are in EIA-608 format.
