Hi,

I don't speak MobileMyth or know if you build it from source, but:

Look at the very last item in the 0.28 release notes. It applies to
anything that has CommFree in the response (but doesn't say that)
and then in:

     https://github.com/jheizer/MobileMyth/blob/master/MobileMyth/App_WebReferences/MythDvr_27/xsd16.xsd#L27

Not sure it's an answer, but I'd try changing the int to a boolean in
the source. I know it affected the Android product but don't know where
the 'System.FormatException' above is generated. git grep CommFree
will give you this:

MobileMyth/App_WebReferences/MythDVR/xsd12.xsd:      <xs:element minOccurs="0" name="CommFree" type="xs:int" />
MobileMyth/App_WebReferences/MythDvr_27/xsd16.xsd:      <xs:element minOccurs="0" name="CommFree" type="xs:int" />
MobileMyth/App_WebReferences/MythGuide/xsd6.xsd:      <xs:element minOccurs="0" name="CommFree" type="xs:int" />

I didn't look at GetUpcomingList, but the expectation is
for 3rd party apps to look at the WSDL at run time or at
least with version specific code.

GetEncoderList output looks the same for my test v0.27 and v29-pre hosts, however
they only have a single dummy encoder on them.

There's also a link in the Release Notes to:

     https://www.mythtv.org/wiki/API_parameters_0.28

that lists the differences in the input parameters (thanks to PhilB.)
