My N810 works really well in almost all regards. It is a great device! The only thing I have ever done with it that didn't work out as planned was to install the screen rotate utility -- that caused an unexpected change in the way the power button works. Otherwise I have not altered it or customized it in any way except to use a few Extras such as Tear. My device is "stock" (i.e., unmodified).

However, I cannot play many video formats. I have mytube installed, but when it downloads a video, it will not play. When I open the .flv file directly, the media player tells me the format is unsupported. The same is true for iPod formatted videos (.mp4) and everything I have tried except mpg videos.

It seems everyone else can play almost any video format without doing anything special. In particular, I see others using mytube and mp4 files. My N810 won't play these.

Any suggestions?
