Well i'm feeling a bit dumb now...
Gave up and went out to do some things while i waited for a reply from you guys. While i was out I tried from my phone (which i did before but from home) and voila! there was the cam stream all working !
It seems trying to connect to WebCamXP before while my phone was on the internal WiFi so the http call had to go out and then back in .... it got blocked/lost somehow. Doing the same thing from outside the internal network works fine.
No idea why that is so ... but it it working and i am happy !
Thanks so much for your support and really informative site.
