Wide World of Women

I just bought the full HD camcorder HDC-SD 10. When I direct the camcorder to dark areas, the screen shows noise (like it were raining).

I copied the videos recorded with it to the PC. The video displayed was'nt as good as I had with the camera HD DMC-FZ28. The HD camera video was more clear and more accurate than the Full HD camcorder! (when not using the zoom)

The seller told me that that happened because my PC couldn't see Full HD. But I can see other FUll HD videos very well.

Here's a cap of a vid taken with that Full HD camcorder:


All full HD camcorders have this problem? Is this rainy noise normal on the screen?

Thank you in advance.
