I can not stream videos on your website, How to fix it?

In order to stream content directly from the site, you need to have a broadband Internet Connection such as DSL or Cable. Unfortunately, dial-up connections are too slow for streaming videos. If the video is freezing every few, try waiting 30 seconds before clicking the play button again. That should give the player enough time to buffer enough video in advance to play without stopping.

How do I download videos to my computer?

To download a video scroll down past the Watch Movie screen to the Download options. You will see a choice different formats (HD, WMV, Mobile). Select the format you want to download by right clicking the link and selecting "Save Target As". You'll be prompted to choose a place where to store the movie on your Hard Drive (remember where you download it of course!), and then the download will start. To play the video, you'll simply have to double click on the file once its completely downloaded.

I can't play/view videos, how can I fix that?

If you can't watch the videos, you have to install the K-Lite Codec, you can download it for free HERE. If you still have problems, download latest version of Windows Media Player.

Can I keep the videos I download forever?

Yes, we do not use DRM technologies to restrict the use of the videos you download from us.

Can I stream the video online by using my iPhone just like youtube?

Yes, We support PC, Mac, Samrt TV, iOS and Android Devices to view the video online just like youtube.

I'm getting extremely slow download speeds from your servers. What's going on?

Our servers have enough capacity to provide fast downloads for all our members. However, the way data packets travel through the Internet means that a small fraction of our customers experience poor download speeds. If you're getting very slow speeds (less than 200 KB/sec) from us but not from other sites, then you're experiencing this problem.

Can I download files and watch them on a Mac?

Yes. Our videos are provided in MP4 and MKV format. You can watch it in Mac, Windows, Chrome OS, Linux.
