Apple has released iTunes 8.0.1 that fixes several important issues. The 58.5MB download, available through Software Update, primarily addresses a flaw in iTunes TV episode downloads which would inadvertently overwrite the HDTV versions of shows with the additional standard-definition copy meant for transfer to iPhones and iPods.
It also mends problems with the new Genius auto-playlist feature, including maintaining seamless playback while starting a new Genius playlist from a given track. Syncing these playlists with iPods has also been improved.
Other updates include better update checks for software updates through the App Store, syncing spoken menus to fourth-generation iPod nanos and better accessibility through VoiceOver in Mac OS X.
