I have a Sony DVD player (about $25 on sale) which has been used to watch
movies about a dozen times. My wife is making DVD copies of our family movies
from VCR tapes, on a Sony video-to-DVD machine, model VRD-MC6. Sometimes the
copied DVDs work on the DVD player, sometimes they don't, and when this happens,
the DVD player loads but does not start the disk.
Question: is there any information or rumors out there that home-made DVD disks
can damage video equipment? Now the DVD player only sends audio the the TV when
playing store-bought movies on DVD.
I used to put music on CDs for playing in the car. The CD players in our two cars stopped working.
Anyone else have similar experiences?
Update: trying two different HDMI cables gave the same results: "unsupported signal" on the TV screen. I connected the RCA cables from the DVD player to the back of the TV and it plays OKAY.
We'll use it with those cables for now.
I am not aware of a disc damaging a player. If it is not compatible it just is rejected by the player or skips. Blank DVDs (they come in DVD- and DVD+ types) are not all created equal and can have compatibility issues with different players. Cleaning discs can sometimes damage CD and DVD players. I think your expectation that a $25 DVD would have any quality control at all is unrealistic. If you can't find a problem with the cables then hopefully you can get it replaced under warranty.
