Sony rdr-vx515 combo vcr/dvd player recorder

You could buy one on E-Bay. Click on the link below, but if you really finalized the DVDs, they should play on other components.
The Sony like yours below is $149.95 and you can buy it now, not bid on it as normally done on e-bay.
Last resort you can take them to a video transfer service, so all is not lost.

Hi and welcome to FixYa

Initially, postback the model number of the Comcast digital adapter and the TV.

Offhand, if the Comcast digital adapter is connected to the Sony through a coaxial patchcord, then the Sony would really have to be set to Ch 4 (or 3). Channel selection is done on the Comcast digital adapter. It is not possible to record one channel while viewing another.

Good luck and thank you for asking FixYa

This is quite common of older players. Some only work with DVD+R discs and others with DVD-R discs.
Some player also does not read recordable discs (an early form to try prevent piracy)
Also make sure if recorded on your Recorder, that the disc is finalized before you try to play it on an older player. (See your menu / manual on the recorder for the procedure)

Purely gear problem. The ejector either ran out of alignment or belting has worn out. Solve this issue and ur player will work perfectly again.

turn off close captionin on your dvd or your tv

set the remote comander for code imput mode press set and menu when the set light are on enter the code number then press enter before you enter the code num press dvd or vcr then press enter sony

Please look at bottom area of remote control there you would notice DVD mode switch, set it to DVD-3 and remote will work with player.
