Some of the talkgroup IDs you have listed are not valid for a Motorola Smartnet system like Ft. Worth's. All valid Smartnet IDs should convert to an odd hex number (drop the 0 LSB). So if your scanner is stopping on a non-valid group, it probably didn't decode the ID correctly from the control channel (common with older trunk trackers), and what you're hearing is probably an image of a valid talkgroup.
These IDs you listed do not convert to an odd hex number:
