Downloads are very slow. Movies shows and youtube freezes up

first reason may be ram of your tv is low
2nd reason may be internet connection is slow

Could just be something as simple as slow internet connection at that time. Netflix does require a buffer of a certain amount of time in the show before it starts, or plays. If the memory buffer empties below that point, the show will freeze until it is back up above that point. I'd check to ensure your internet is operating at the minimum for nextflix when you're playing the show.
One tip would be to ensure that if it's happening, that nothing else is trying to connect to the internet and that no downloads are occurring.

Do you have anti-virus software installed? If not, you may be infected, and your system is being used by the virus to send out spam e-mails.

Need more information to really help you. Are you playing movies in the DVD/CD player of the laptop? Are you playing movies by streaming from Netflix or Amazon or Hulu or Xfinity? Are you playing movies from an external hard drive or flashdrive plugged into an older USB 2.0 port?
Your wi-fi connection may be too slow to stream without freezing. Your cpu/processor may be too old and slow to handle HD video. Your video/graphics chip built-in to the laptop may be old and not capable of handling HD quality video.

Hi,
can you please tell me your Flash version?

can you please tell me when did this start to happen?

Sounds like slow connection speed to me.

The reason behind the slow working is 'buffering of video'.
