Does anyone know how to download from jibjab?
Edit: Never mind, found out. The url to the flv file is in an xml file.

eddy · Post by **eddy** » Tue Aug 21, 2007 2:29 pm

Next update :
---------------
- auto-detect source
- download through IE frames ( it will fix GoogleVideo problem )
- support : myspace or metacafe

Thank you very much for this Droopy

jack · Post by **jack** » Mon Sep 08, 2008 4:01 am

pardon my ignorance, but how do you download a youtube video?
if I enter a url of a video all I get is a message that such videos are not available.
and what about the last download link, it's dead.

Inf0Byt3 · Post by **Inf0Byt3** » Mon Sep 08, 2008 10:42 am

It could be that YouTube has changed the location of the file or the specifications. They usually do this to kill usch programs so people can't download the videos (they lose bandwidth and noone clicks their ads).

Fangbeast · Post by **Fangbeast** » Mon Sep 08, 2008 11:54 am

Sounds right. I just tried this after fixing a few little bugs for pb4.2 and absolutely nothing showed up.

Going to fiddle with the URL analysis area unless the original author steps in. Wish me luck:):)
