Picture Problems when Running in Full Screen 
With a lot of systems often used now, some people will find themselves unable to stop video issues when operating in full screen mode, but you can still take steps to reduce the lag.The problem normally causing streaming lag (at least in full screen), is the users hardware acceleration, so lets begin with turning that off. This should prevent freezing of video’s during .flv video playback. It couldn’t be easier, just right click on the flash video player’s screen, then a options menu pops up you just click on enable hardware acceleration so as to make sure it is no longer active.
Of course, even without full screen play back problems, it could be a case whereby some viewers will naturally prefer to watch films in windowed mode. It isn’t uncommon for images to be specifically made for windowed mode, as such full screen can often cause the stretching of a movie, causing a break down in video quality.
How to troubleshoot Issues with Sound Resolution
The most common problems related to volume are related to the fact that the standard audio settings of movies differ greatly when out on the web.
When this issue happens all you can really do is turn up your hardware and software, and hope you are able to hear enough of what’s going on to continue to enjoy the film.
The above answer is probably not what you wanted to find out, but if you are still having problems do not cry all is not over. It could be worthwhile to install a sound amplifier program such as Ozone for Winamp, which should improve sound volume, as well as clarity, when you watch movies or other streams via the internet.
