They claim to support MP3, WMA, RM, AAC, AVI, MKV, RMVB, DIVX, XVID, MP4, MOV, WMV, 3GP and MPG - an impressive list to say the least. It has a very similar file transfer method as CineXPlayer however has the added feature of streaming over your home network. This works extremely well through FTP and is very simple to use. You basically set an IP address on your iPad that allows access to OPlayers file directory over FTP. The process then becomes as simple as following the address in an browser and dragging and dropping files into the application. This is extremely useful for adding media from computers without iTunes installed.
If that wasn't enough there is also the additional support of streaming from your PC/LAPTOP/MEDIA CENTRE over 3G and Wireless. In practise I found this to be quite temperamental.
However all in all, this is a well rounded App and supports plenty of formats. I still found CineXPlayer's playback to be smoother but this shows a step in the right direction from developers.
Now all we need is a VLC media player for iPad.....
