Hi Ravi,
It would work but it would be very inconvenient because you'd have to go into the DVD player setup menu to alter the individual volume levels of each channel every time you wanted to adust the sound levels. If you use an amp with an input level control, it would be easier but still inconvenient. There are older stereo power amps around that have input level controls but they are never convenient. I don't advise you do this because there's a real danger that the output levels might be too high and you could drive the amp into clipping and damage drivers in the speaker.
Regards,
