These lines are for handling the SI pointer field. Data is the pointer field, which contains the byte offset to the actual data (usually 0). "+ 1" for the pointer field itself. The order of the two statements need to be reversed. First fix the length, then the data pointer: Length -= Data + 1; Data += Data + 1; Cheers, Frank _______________________________________________ vdr mailing list email@example.com http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
