If you like to use software such as PPStream to watch the video, then you will find that these software in Windows 7 may not be able to play the online video, the symptom is to double-click the corresponding video can not be normal display image, but stay in the screen of ads, annoying.
In fact, we have an easy way to solve this embarrassment. Casually find a WMV format video file, if you can't find, you can enter the "\users\public\videos\sample videos\" path to any choice, such as bear.wmv, the WMV file copied to the PPStream installation folder. Next, right-click the PPStream shortcut on the desktop, open the Properties window, position the cursor in the text box after the target, and add "Amazing_caves_720.wmv" after the shortcut, where "amazing_caves_720.wmv" is the name of the WMV file you just copied, notice that there is a half-width space in front of it (see Figure 5), then close the Properties dialog box after confirming, and then play the online video smoothly.
