Ps3 Play Tv

I recorded some TV shows using television play PS3 and I wanted to copy them to my external hard drive or USB drive, is it possible?

No you can not, I fear.
It was said that you could at first, but the only way you can watch them away from your PS3 is in "Remote Play on your PSP.

you can register in a memory stick, but not an external hard drive. If you want to save an external hard drive, you must register first in the memory stick, then save it to the external hard drive from the memory stick.

Yes, but it would require a huge memory capacity.
