Hi Michael,
Thanks very much for your help with this.
This is what nettool recorded when I used Poster:
POST /SkyPlay2 HTTP/1.1
Host: 192.168.1.250:49153

This is what nettool recorded when I used your python script
POST /SkyPlay2 HTTP/1.1
Host: 192.168.1.250:49153
Accept-Encoding: identity
SOAPACTION: urn:schemas-nds-com:service:SkyPlay:2#SetAVTransportURI
Content-Length: 409
Content-Type: text/xml; char-set=utf-8
<?xml version="1.0" encoding="utf-8"?>
<s:Envelope s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body>
<u:SetAVTransportURI xmlns:u="urn:schemas-nds-com:service:SkyPlay:2">
<InstanceID>0</InstanceID>
<CurrentURI>xsi://fa6</CurrentURI>
<CurrentURIMetaData>NOT_IMPLEMENTED</CurrentURIMetaData>
</u:SetAVTransportURI>
</s:Body>
</s:Envelope>
As you can see, the two conversations are different, I'm pretty sure that, even with my limited knowledge of python, once we can get the channel change part working correctly, I can do the rest to accept the channel number as input and then use a lookup table to get the correct hex code to send to the Sky box. I think I'll even be able to interrogate the box to find out what channel it is on before and after the script runs (which is important, because there is an error generated if I try to switch to the channel it's already on.
Regards,
Dave.
