A recent post on LifeHacker mentioned a little program called MPlayer, which allows you to play nearly any media file (like RealAudio/Video, Ogg, & M4A) on your Windows Mobile 5 or 6 phone. However, the post mentioned the program was a rough port of a Linux version of the app, and was somewhat of a killer on processor (and thereby, battery) usage. However, a commenter mentioned another program called Conduits Pocket Player, which they liked better, so I thought it was worth checking out. The Conduits Pocket Player, although not free (it's $19.95), supports all Windows Mobile devices and offers a myriad of features. The Pocket Player supports MP3, WMA, WMV1 2, Ogg Vorbis, FLAC, WAV, Protected WMA, u-Law, A-Law, AU, &ADPCM WAV formats. It also has a Media Browser menu system with touch scrolling & gesture support; a Media Library with ratings, an auto-imports up to 1000+ tracks; an internet radio web guide for finding mp3 blogs & podcasts; voicemail playback as WAV attachments which integrates with your inbox; a skinnable player with visualizations and album art support; a playlist manager; bookmarks; a sleep timer; and so much more! If you're looking to do more with your smartphone, this looks pretty cool!
