The S60.com's guys did a great job (thanks Jukka) making some studies to know how well S60's current applications cope with popular Internet streaming video sites.

Here are some issues we have identified so far, and some thoughts on how service providers could help out mobile users already today.

1) Pay attention to your HTML/JavaScript/Flash

2) Use a mobile-friendly video format
Many of the most popular sites use Flash Video (like YouTube or Google Video), it's not compatible with mobiles. S60 supports MPEG-4 and RealVideo for streaming, both are widely supported by PC players also. MPEG-4 AVC is rapidly gaining popularity, not least because iPod/iTunes have embraced it for downloadable content. In our study non-supported video format caused 23 percent of problems.

3) If using embedded media player, provide alternative link

4) The rest

Ok, here are the problems, what about solutions? Here are some of the things S60 is doing to improve the situation:
1) Embrace AVC video codec. Many of the S60 3rd Edition devices support AVC, and we are adding it is a standard codec during 2006.
2) Improve the browser. The new S60 browser is already included in most S60 3rd Edition devices, and it will be the only browser in the next release, Feature Pack 1. This browser shares the same rendering engine with Apple's Safari browser, we are quite confident about it.
3) Support embedded video. This will be included along with the new browser in 3rd Edition, Feature Pack 1.
