Pixelating recordings?

[bagmand]

Hi,
I´m using a DENVER DVB-C box to record HDTV TS-streams.
Problem is, that the signal is perfect when watching while recording and not recording. But some recordings turn out pixelatet?
Anybody knows what causes this? I´m using a Kingston usb 3.0 pen 64GB.

Shouldn't the box just record the digital stream so it should be same as watching it?
Or are you using something to capture the stream to the computer?

But Denver products are not that great...

Thanx for fast reply.
I really don´t know. It´s weird. I´m recording to a USB pen, and then transferring it to my computer, to remove commercials.
I´m gonna try a Clint box. It´s a little more expensive, but maybe worth it.
