+- __MMT Media__ - It is believed that the MMT parsing works, but it appears
+that no station is actually transmitting the signaling necessary to make it
+actually function properly.  A work-around is implemented but it only gathers
+the audio/video parameters some of the time, and should not be considered
+reliable.\\
+- __ESG Support__ - Some stations still do not have ESG data showing, or it
+is not showing complete ESG data.  This will continue to be reviewed in the
+future.\\
+- __eGPS Support__ - The code displays eGPS raw data, but the data seems to
+be in a proprietary format with little or no public documentation.  Attempts
+to reverse-engineer the structure beyond minimal header support have been
+unsuccessful.\\
+- __Bitrates__ - While the usage chart shows the total data and number of
+packets in all cases, bitrates are currently unreliable.  For debug and IPv4
+input formats, the necessary data is missing and probably cannot be reverse
+engineered.  For other formats, the calculation has not been validated.\\
