There are different ways to bypass MegaVideo 72 Minutes limit, you can change your connection IP, by turning your modem on and off, but that doesn't work if you are using a static IP, for instance, if you are using a computer in a network, most likely your IP is static. Now if you are using wireless card, your ip is probably dynamic so turning your modem off, waiting 30 seconds and turning it on again should change your IP and you could be able to watch the rest of the videos.
Damn you Megavideo!!! *shakes fist*
Another way to bypass megavideo 72 Minutes is by downloading the video to your computer, you can use Firefox and DownloadHelper for that and then download a free FLV Player *It's Highly Recommended to install a FLV Player on your computer*.
Now if you don't want to install any other software on your computer, or you can't, try this:
Step 1: Click PLAY button of megavideo episode, click PAUSE and wait for the video to buffer to 100%.
Step 2: After the video is done buffering, go to your menu bar on your browser, and click on File > Work Offline.
Step 3: Enjoy the episode.
Step 4: Unclick the “Work Offline” button and do the same with other episodes.
Or you can download and install Hide My IP, it is shareware but you can try it 14 days for free (so is not a long term solution, unless you buy it), but it will help you watch the episode without 72 minute's restriction:
And it doesn't have viruses, spyware, or any thing like that, so don't worry about your privacy, the software is to HIDE you! So it cares for your privacy. See it in action:
I hope it helps, I'm going to try to the most to get videos from another streams other than MegaVideo, no the chinese ones, but in the meanwhile you'll have to handle to bypass Megavideo's 72 Minutes Limit.
