If you have good internet connection on your mobile, you can watch these streams on your mobile phones too. The following steps explain how to watch live mms streams on mobile phone.
I am going to explain how i watched mms stream on Nokia N97. For example I found this mms://online.ntdtvcast.com/Stream-Live mms stream on net. I watched this stream using windows media player on PC.
To watch in mobile, open default internet browser. open the mms url on the browser. Now automatically real player opens and play the live feed. You can watch rtsp (rtsp://) streams also like this way.
Some streams urls starts with http:// . for example that looks like this 'http://streamsite.tld/stream' . If you try to play this feed using above method. That will not work. Try removing "http://" with "mms://" in the url and follow the above.
Using this way you can watch Live TV Channels on mobile, if they provide MMS Stream.
If you want to get the mms url from a live video web page URL Snopper Freeware may help you.
