I have made only one experiment with SmartMovie, finding it much better than RealPlayer, especially when Crop mode is Full. I may even consider to watch a movie done with it - but only if I am coerced to do it. But with RealPlayer - never.
After exhaustive review of different movie players for the 9300, I decided upon SmartMovie from LazyCat software.
You have to convert the movies on your desktop computer to play, but the quality is outstanding (better than the video iPod!).
I don't know of any generic movie player that can handle all of the different formats that are out there.
Another outstanding feature of SmartMovie is the user interface of both the player and the converter. The player can remember where you stopped watching and start back up again. Brightness and volume are also adjustable.
The converter can resize and crop your video stream so you can get the black bars of the letterbox format out and have more image on the screen.
The only drawback that I've found with SmartMovie is exiting the program. Because it sits top-level (high CPU access), you sometimes have to exit twice to stop the program.
I've never found the Realplayer to be of any real value for video, but it does come in handy if you find an audio stream on a website and you want to play it.
