Ok, I changed the analog table's interface handler back to how it use to be
(ie: no MFD_SKIP logic) and added the logic you recommended to return MFD_SKIP
to the analog table's "get" handler for the ProtectionStatus field.
Seems like we are trying to verify whether the field (column data) is truely
related to the "Analog Table" or not by determining whether the
ProtectionStatus field is 0. Keep in mind, a ProtectionStatus field value of
"0 - copyProtectionOff" is a "valid" field value when the row is related to the
Analog Table. As a result, I do not believe if I can simply check for a "0 -
copyProtectionOff" value to determine whether a MFD_SKIP value should be
returned. Perhaps you are just having me add this logic to acquire some more
traces only? I just wanted to mention this to make sure you understand this
point.
Also please remember the Analog Table (ie: Table2) plus multiple other tables
(Table3,4,5) extend the main AVInterfaceTable (ie:Table1). The data_context of
Table1 is defined to include a "union" of the Table2,3,4,5 structures. As a
result, I am not sure I would be able to check for a value of "0 -
copyProtectionOff" if the row is "not" related to the Analog Table since the
memory might be populated with some other value from Table3,4 or 5 ..... since
it uses a union.
For the trace, I added a couple of "printf" statements which you will see in
BOLD:
"SKIP ROW" = located in row_prep() to indicate which row was skipped with
MFD_SKIP
"SKIP_STATUS" = located in ProtectionStatus_get() to indicate the in
ProtectionStatus was found to be "0" and that a MFD_SKIP was returned.
Now, here is the trace output you requested:

Hmm.. ok.. now lets try something a little bit different... comment out the
code we added to the analog table's interface handler for dealing with
MFD_SKIP, and in the ocStbHostAnalogVideoProtectionStatus get function, add
code along the lines of
if (status == 0) /* copyProtectionOff */
return MFD_SKIP;
Then do the getnext again, and send the results again. (returning skip from
each of the get routines should work, but it's obviously not a very efficient
option. I'm hoping the debug output will reveal an interesting difference.)
