If for any reason you can not access the .avi sample file through FTP you may right click this line
and select 'save as', or 'save target as' (it downloads in about 2 minutes on my cable connection).

The video which plays on this page is from longtailvideo.com because the one which is included with the player
download does not correspond to the aspect ratio in the code given at their setup wizard page.

Please modify the player settings to achive best HD quality result with the sample file converted to .flv.
Feel free to upload to server script/files which you consider necessary to obtain HD quality.
If you think that it is possible to achieve better result by saving the original .avi file
with different settings (still maintaining the 16:9 aspect ratio and staying as close as possible
to 640:360 screen size) let me know and I will happily generate and upload a new sample file.
