How can anyone watch a movie through TV speakers. 80% of a movie experience is surround sound.
I would recommend buying an ARCAM surround receiver. If you can afford their G amplifier technology I would do that. First 50 watts is pure Class A. Then buy some decent speakers.
then watch Saving Private Ryan. You can hear bullets passing by your ears.
you can also hear 2 channel music through your ARCAM. Very good sound.
