I've used this product for 2 weeks, and I must say the video play back quality is great! It also provides you with ways to manage your own videos. But still there are too many bugs and disadvantages.

You have to upload video to their server, this may take 24 hours to have your video on your site. If you use too much bandwidth then you have to pay for it. Jvideo Player always stream from their streaming server even if you watch your video 2nd time, it doesn't cache on the PC. There are no STOP button on JVideo Player so your PC always streaming from the server even if you don't want to watch it anymore, PAUSE mode still stream as well. Can't play other videos besides from their own server, that means more bandwidth being used, and eventually you have to upgrade to pay account. You can't play video from other sources like YouTube, Google etc, that means to play video with other sources then you have to use a different Video Player (not Jvideo), that means inconsistant of Video Players on your website, one to watch YouTube, one to watch your own videos from their streaming server.

Anyway, I like the video quality, but uploading video to their Streaming Server takes time, sometimes upto 24 hrs to have it available on your website, that's just too long. Video only play in streaming mode, meaning using alot of bandwidth on the user's client side, and also using more streaming bandwidth, which will leads to pay account.
