Info about SlingPlayer Mobile for BlackBerry Listen and Letterbox options
SlingPlayer Mobile for BlackBerry Settings
In Settings, you can personalize the way that SlingPlayer Mobile connects and then shows you your audio/video programs. Here are two settings that you may find especially useful:
Listen: If you're not watching video at the moment, choosing Listen conserves bandwidth and may provide slightly better audio. This setting works like a toggle switch. When you choose this mode, the control "toggles" and changes to Watch. Choosing Watch brings the video back again.
Letterbox: These days, TV programs and movies are recorded in several different formats. They can be in Standard format, which has its ratio of 3:4. They can also be in widescreen format 16:9. With the Letterbox option, you can determine how you want the video to appear on your TV screen. If the picture looks too narrow and overly-tall, choosing the Letterbox setting may help. It causes the screen to adjust its aspect ratio for the widescreen-format program that you're watching.
