YouTube to Mp4 Player?

its been suggested that I use keepvideo

29-99 Usd$ for the software 2 units needed so thats 2 times $29-99Usd for this.

My Mp3/Mp4 2GB media player is by Vizion yes I know you never heard of that brand

Is there a decent user Mp3/mp4 player user friendly good technical support,long battery play life?

Or should I just invest in a Portable DVD Player instead.

I am interested in downloading Live Streaming Video Content from YouTube by the way.

Thanks ,

Heidy
