Make it possible to turn off video frame linear interpolation. Traditionally Showtime have interpolated video frames to match display output. Some users find that this may blur the video a bit so this feature can now be turned off.
Store per-file settings directly in file system. Read more below.
Playstation 3 specific changes Showtime now uses virtual memory (backed by HDD) on PS3. This should drastically reduce out-of-memory problems.
Show a notification if h264 profile/level restrictions is violated.
For example if a 1080p video use more than 4 reference frames.
Per-file and per-folder settings During video playback the user can adjust per-file specific settings.

Audio Volume (New in 4.6)
Audio/Video sync adjustment
Subtitle sync adjustment
Subtitle scaling
Subtitle alignment

The settings are remembered per file so when you come back the configuration will be resumed. It's now also possible to apply the configuration to the entire folder. This means that any files loaded from that folder (including new ones) will also have these settings. The user can also apply the current settings as new global defaults.
If the files are located on a SMB/Windows share with write access the corresponding settings will be stored on the server. See below.
Store per-file settings directly in file system using Extended Attributes. Up until now, Showtime have stored per-file settings in an Sqlite database. These settings include things such as "Seen", "Resume position", "Selected subtitle", "Selected audio track" plus all the settings that can be configured during video playback (mentioned above).
Starting from 4.6 Showtime will now try to store these settings directly in the filesystem where the file is also located. It does this by storing the information as "Extended Attribute". This works if Showtime have write access to your SMB/Windows shares. This feature is default on and can be disabled in Settings -> General.
The real upside of this is that if you have multiple devices they will all share the "Seen status", "Resume position", and all other settings. Also if you re-install Showtime this information will be intact.

Internationalization Add support for BIG5 character encoding
Add support for different On Screen Keyboard layouts.
