Samsung HT-E4500 blu ray blank DVDr disc playback problem

Helo,
First post here and i'm hoping someone who has the same player can help.

I just bought this a couple of weeks ago and i'm having problems getting a decent blank DVDr disc to play reliably on it. (not interested in burning blu ray)

I use DVDFab (have done for 3yrs) and have never had problems backing up my new dvd movies. For the last 3yrs they would play fine on my panasonic dvd player. Now it is a real lottery trying to play them on the Samsung.

I have tried various medium but get the same results. Pixilated, stop for a second, jump a couple of frames and continue or just stop and refuse to go any further. sometimes they play fine until the last 10mins and then give up and freeze and sometimes the same brand plays fine. It is very annoying.

Does anyone have the same player that has a tried and tested branded DVDr medium? I have tried TDK, JVC, Intenso and maxell. (All played fine on the old panasonic player)

I just want to insert, press play, open a beer and watch a movie without my fingers and toes crossed i am going to be able to watch it to the end.
