1. Acquire a streaming internet player at a retail store or online. Streaming internet players allow you to stream movies and tv shows from Netflix, videos from YouTube, and music from Pandora, among other options. Different streaming internet players include, but are not limited to:
   • Apple TV
   • Roku
   • Boxee
   • Sony Streaming Player
2. 2
   Plug the player into its outlet. Power it up in order to hook it up with your TV and get it connected to the internet.
3. 3
   Connect your streaming internet player to your TV. There are several different ways to do this:
   • Connect with an HDMI cable. If you have an HDTV, you'll probably want to make use of that sparkling resolution by purchasing an HDMI cable and hooking the cable both into your player and the back of the TV.
   • Connect with a standard A/V cable if you don't have HDTV. Match up the yellow/red/white ports on the back of your TV to the video and audio cables.
4. 4
   Connect to your network. After turning on your streaming internet player, you'll want to connect to the internet. Most streaming internet players nowadays come with wireless internet setup, meaning you don't have to go through the hassle of plugging cables in everywhere in order to get a signal. Simply type in your internet name and password into the guided setup when you turn on your device.
   • If you don't have wireless internet capabilities, you're going to most likely connect one end of an Ethernet cable into the back of your streaming internet player, and the other end into an open Ethernet port on your router.
5. 5
   Finalize your setup. You've got power to your streaming player, you've got it connected to your TV, and you have internet. Consider a few other options before you start watching Netflix from the pleasure of your couch instead of your PC screen.
   • Download any of the latest software offered by the streaming internet player. This could help expedite things and offer cool perks.
   • Choose your video output resolution. Especially helpful for HD nuts.
   • Consider linking the player to your online account, if possible. Some players will use social media to share what you watch with your friends, as well as offering suggestions based on what your friends are watching.

Hi

Download the latest version of Flash Player from www.adobe.com.

The efficiency of video streaming is determined by more than just the flash software.

Other issues that effect efficiency are:

The bandwith of the internet connection

Streaming during peak internet times

The power of your CPU

The amount and power of your RAM

The power and quality of your graphics card.

The optimum solution is to invest in a media player with dedicated storage and let the player's resources relieve some of the pressure on your notebook's resources.

i hope this helps

Doing my best to give you a correct solution and understanding
Issue : delays in streaming video
Environment :
ISP : Bellsouth
Router : wireless WRT150N
Solution :
"Downside to streaming"
Traffic jams.
Internet isn't a direct pipeline from the source to you. Streamed content passes through many other computers on its way to your computer via your ISP. If any one of them is carrying too much other traffic, the streamed content may be interrupted and pause. Streamed content is "buffered" to help avoid this, but sometimes it's unavoidable.
(test the downstream and upstream speed and alose test the download )
(Checked deleting the temporary files and folders)
(Checked firewall and Anti virus)
A slow computer :
if you have too many applications open, it could slow down your media streaming. If you notice things are sluggish, close all unnecessary applications and windows running on your computer. Just keep your Web browser and your media player open.
Noisy phone lines.
phone line that isn't free of noise (humming, crackling), that's not good for streaming (or Web browsing). Disconnect any phones that cause a buzz or hum.

Streaming audio/video quality can be affected by connection rate and Internet congestion. Many types of interruptions between your computer, your player, your computer's OS, your local network, your ISP and a streaming server can exist and cause trouble....
When you listen to the live audio/video stream, the sound or video skips, cuts out or buffers if the player doesn't have enough network bandwidth, it will buffer. Try increasing your player's buffering setting.Also:

• Make sure you are choosing the appropriate bandwidth version of a media stream based on your Internet connection.
• Make sure you are choosing the appropriate bandwidth settings in an Internet media player or streaming audio/video recorder.
• Make sure NOT to download applications or files while watching/listening to media streams. Your Internet connection is shared between all open applications including your web-browser, your download manager and your streaming player. Closing applications that use your Internet connection simultaneously with your streaming player may reduce buffering.
• Close other unnecessary applications that may be open on your computer. Reboot your computer. If you have lots of other programs open, they may be using too much processor time and/or RAM for the player to work properly.
• Make sure your Internet connection is fast enough to reliably listen to streaming audio and/or watch streaming video online. High speed Internet connection is recommended.
• Make sure your computer is fast enough. If your computer is old, it might be too slow to play an audio/video stream regardless of what else it's doing.
• Update your media players and streaming audio/video recorders regularly.

Internet congestion can slow down the delivery of the stream, make it difficult for you to connect or cause buffering. Often the interruption is temporary. Please try to connect a few times at different times of the day, if possible. If you repeatedly have problems connecting, please notify your ISP - there are often quick fixes they can make when they learn about your issue.

Try the above steps you will find a solution to your problem....100% it will work.....
