Jamawkinaw Enterprises has released version 1.0.10 of its Downcast podcatcher app with new options for sorting local episodes by time remaining and file size. It also adds a 1.25x playback speed option and an episode count to the Local and Available episode lists. The release also fixes a bug that prevented episode duration from displaying, an issue that prevented sharing via email, a problem that caused authentication failures for password-protected podcasts (which may require you to re-enter your credentials), and a couple of bugs associated with playback speed settings. As of this writing, the Mac App Store had not updated Downcast to version 1.0.10. ($9.99 new from the Mac App Store, free update, 6.4 MB, release notes)
Improve Apple Services with AirPort Base Stations
You can make iChat file transfers, iDisk, and Back to My Mac work better by turning on a setting with Apple AirPort base stations released starting in 2003. Launch AirPort Utility, select your base station, click Manual Setup, choose the Internet view, and click the NAT tab. Check the Enable NAT Port Mapping Protocol (NAT-PMP) box, and click Update. NAT-PMP lets your Mac OS X computer give Apple information to connect back into a network that's otherwise unreachable from the rest of the Internet. This speeds updates and makes connections work better for services run by Apple.
