Video Playback / Recording Devices

I am considering buying a dvd duplicator, i need to know if the burn speed slows down if you burn a lot of dvd media, like on a pc if the dma settings change.

I have a Samsung DVD-VR330 and it's becoming temporamental.  I've been using Pleomax (by Samsung) DVD-RW discs to record from TV.  They have been fine - most times - but over the last couple of months it is refusing to load some of them, wanting to re-initialise them and then when I tape on them it wants to initialise again, thus I lose the film.  Can anyone help solve my problem?  I've even cleaned the disc drive to be sure it's not that.

My Toshiba 36 inch HD TV does not always turn on either with the remote or the on/off button. The little red light on the tuner button flashes and the tuner makes a clicking sound. After about 10 or 20 times, the TV may turn on. I'm refering the on/off button as the tuner. Nobody in my area repairs TV's and the nearest repairman is 60 miles away. I called one guy and if I bring the TV to him, he charges $60 just to look at it and will apply that amount to the bill if he repairs the set. He would not give an estimate and I don't know if the TV is worth fixing.
