[G4] Do I need a new DVD Player?

[Richard M. Kriss]

Something tells me the old RCA DVD Player we have on top of the RCA Home
Theater may be old stuff and needs to be replaced as it will not play DVD's
that play on my G4.

As a test I burned a movie we own to a DVD+RW disc using the PIONEER DVD-RW
DVR-109 and it plays perfect using the OSX 10.4 DVD Player.app but will NOT
play via the RCA set top box DVD player. Could the issue be I used a DVD+RW
rather than a DVD-RW disc?

Any suggestions on what specs are important in the newer TV DVD players? I
would like to stay with an RCA to be able to run everything from the same
remote.
