Why Can't I download these YouTube Videos?

I am using latest FRD with plugins.

I download several YouTube Full Movies without any problem using FRD.

But I can't download the videos of Anamika & Aandhi even after much trials.
I get the message in FRD, "Can not find specified video format (43)".

Why this?

These are special RTMP videos, which could be otherwise supported, but YouTube uses the RTMPE handshake type 10, which is not (yet) supported by any other software than Adobe's own proprietary Flash player.

Thanks ntoskrnl, for reply.

OrbitDownloader also don't works for the download of Aandhi.

Do anyone know a method to download these videos from YouTube?

No, there is no way at the moment, because only Adobe's Flash Player supports the type 10 handshake.
