This allowed me to do the screenscraping with curl and the parsing on android itself.
For the backend I picked MXplayer, the nice thing about it is that it has HLS support, so you'll be able to stream WeepeeTV on older Android versions too. - I got it running on my HTC Wildfire S (although very slowly, no hardware decoding).
Of course this also allows you to have full screen and you're able to change your aspect ratio.
(The not so nice thing about MXplayer is that it doesn't support https urls, so I included stunnel to do the https offloading)
Some screenshots when running on my 7" ICS tablet.
But for now it works for me.
If anyone is interested in beta-testing this contact me on twitter (@42wim)
