Is DVD Player with progressive scan necessary?

I'm a bit confused ... say I have a TV with progressive scan capability but my DVD player is not. Will it display good image quality (no jaggy, etc)? In other word, is TV with progressive scan capability is already enough?

If not, then I assume both TV and player should have progressive scan. But what if the prog. scan (chip or whatever) quality is different on those TV and player?

DVD players have progressive scan output, tv's have input.

If your DVD player is not progressive scan then your tv would not display the best picture that it possibly could. The image quality is only as good as the player, disc and display device.

But what about TVs that have a built-in deinterlacer chip?

But if, like most new high-end TVs, your TV has a built in deinterlacer (often called a “line doubler”), then the television has been converting your interlaced signal to 480p already, so the smoothness and lack of line structure are already there. So what can a progressive DVD player offer? Better deinterlacing, to start with. In other words, the deinterlacer in the DVD player is likely better than the one in your TV (the DVD player's deinterlacer also performs the deinterlacing in the digital domain right off the disc, rather than sending an analog video signal to the TV, which has to convert it back to digital for deinterlacing).
