does not work with Humax FVP as box only returns first few results (possibly issue with Net::UPnP)

[northernb39]

Humax FVP box does not return the a full list in one pass. It only appears to return upto 20 results. I did some digging and found that:

In the example above the box only returns 20 results, sometimes less but i've not seen more. However it says there are 385 total matches.

I have found it is possible to get further results by setting the tag <StartingIndex> to a number other than zero in the POST. e.g <StartingIndex>20</StartingIndex>

I suspect it could be an issue with Net::UPnP rather than with your code however I don't know perl and I can't work out how to log an issue with Net::UPnP on cpan.

For reference:

• VLC only sees a few as well (I don't think I've seen more than 20 i.e. 1 pass)
• Kodi, from memory, returns all results (takes a while to populate)
• Windoze 10 returns all results (takes a while to populate)
