TCP Media Player
Portable video is fast becoming the most popular secondary use for Pocket PCs, so making sure you have the right media player is now a priority for many Windows Mobile device owners. TCPMP is easy to use, very stable and loaded with a variety of features. TCPMP's main screen is reminiscent of similar programs on your desktop computer, with options to change aspect ratio, zoom and volume as well as more advanced controls such as video speed (10% - 200%), video driver, audio preamp and more.
One issue with playing video files on a Pocket PC, irrespective of which program you use to play them, is that there will be some lag or jumps from time to time. TCPMP's settings help you with this, allowing you to play around with different levels of quality and performance to help you guarantee the best possible multimedia experience. TCPMP is certainly a lot more customizable than most other Pocket PC video apps.
TCPMP is a free, open source multimedia player which we'd recommend to anyone who wants to watch video on their Pocket PC. That said, if portable video is your heart's desire, it would definitely be worth investing in a device built specifically for video playback which will provide much better overall quality.
