Looks like programs like Replay Media Catcher will soon be the only way to download videos from YouTube. TechCrunch’s video download tool has recently been blocked by YouTube, and it’s likely they will start to block other sites.
Here’s the story:
What do YOU do about this? Use a PC-based download tool like Replay Media Catcher, which works free with YouTube. If you want the technical meat of why this will continue to work read on…
The way TechCrunch (and likely other sites) are being blocked is via the IP address of their servers. The server goes directly to the YouTube site, and pretends to be a web browser, and then figures out the download link. It’s easy for YouTube to write a script to block certain IP addresses.
The “client” approach (like Replay Media Catcher) cannot be foiled in this way, since the IP address for the download request comes from an individual user’s PC, and not a server. YouTube cannot tell the difference between your web browser, or a client running on your PC, since the IP address of the request is the same.
It will be interesting to see if YouTube continues to crack down on other sites.
