Query: Disc Error Messages

The manual does not say what speed DVD-R/RW to use. I purchased Memorex DVD-R x8 and received a Disc Error Message. I then purchased DVD-R x4 and received same error message. I emailed customer support and waited two days for a reply. In the meantime I called customer support and was told only media x1 or x2 can be used. When I received the email message message from their support personel it said: " DVD-R 4x can be used 8x will result in a disc error.DVD-RW 2x can be used 4x will result in a disc error.The following discs have been tested and are proven to be compatible with our DVD recorders.MEMOREX DVD-R FUJIFILM DVD-R FUJIFILM DVD-RW IMATION DVD-RWIMATION DVD-R 2.0 TDK DVD-RW 2X TDK DVD-R 2X"So, go figure. I spent a lot of money on DVD-R's that don't work. I'm returning the product rather than continually purchasing non-refundable DVDs. I now have 45 DVD-R's that are of no use to me. Thankfully, Amazon will refund the purchase price of this this player/recorder.
