Do any of these video players read the iTunes-synced videos? I have all of mine stored on the iPad as podcasts. Will any of these apps be able to play the videos as-is or do they require their own memory space/download area? The
TV works fine for practicing at home (slow motion "sticks" until turned off) but the iPad video app slow motion requires holding your finger down so it is not good for practicing at the studio.
Nope, only Azul is capable of that, but it doesn't support slow playback.
(BTW, it's via the first, university hat icon on the icon row at the top right. in addition to audio, can quickly import videos too. It shows the name of the titles but offers no way of traversing via playlists / genre / composer / album etc. (everything is shown in a flat list) Unfortunately, doesn't resolve the name (UUID will be displayed). Fortunately, you can, then, rename the imported title.)
The best is probably jailbreaking your machine; then, you'll be able to use XBMC (which does support slow playback), which can directly enter any directory in the file system. In addition, if you use iFile on a JB'n device, you'll be able to easily cut-and-paste (taking a fraction of second, as opposed to copying) synched video files to the Documents dir of any AppStore player.
