The imaginatively named NicePlayer is er… a media player for OS X. I love it when apps are usefully named… Although actually, the name proves quite appropriate.
It uses QuickTime or the DVD Player but presents the video in borderless windows up to full screen – and without nags even if you haven’t got Quicktime Pro. But the really nice thing about it is support for plugins. The Xine Plugin brings support for MPEG2_ts files (my Freeview TV recordings) and it’s snappier and more responsive the XinePlayer which also lacks the facility to skip forwards and backwards by a user defined interval (ie for ad breaks).
It should be called VeryNicePlayer.
