Can I fix this problem with a toshiba 630 dvd video recorder with recording shows?

Okay so I set up to record a show on DVD then go back to watch it later that night and the first 5 minutes or so is nothing but freezing on the disk. I've tried adding time to the recording with limited success, very annoying.

Please anyone I've looked through the phone book they called a manual and am probably more confused, is there a way to turn off the part about not recording copyright stuff (probably just sports stuff and a like). I quote from the manual The program contains copy protection signal that restricts copying. But that was from the problem nothing was recorded.

My problem more closely resembles playback image freezes for a moment (actually 5-10 minutes at the start) there only remedy during the playback of 2 layered disc picture may freeze for a moment when the 1st layer switches to the 2nd layer. This is not a malfunction. Which makes little sense to me, I use DVD RWs from PK Media technologies.

Okay there's a small tv on top of the recorder and on a smaller metal table beside the recorder is a cable box with a Playstation 2 & 3 underneath.

I'm about ready to take this whole thing back to the store and say the god dam F-in thing don't work money back now. But I do want to try and make it work so please any ideas or suggestions would be helpful. Do I have to buy different discs or what?
