my dvd player has a usb slot and working well but some torrent download movies not playing usually +600mb?

It probably because of the file type. Please check your DVD manual for supported file types.

AVI and VOB are playable in maximum DVD players. If you find out the supported file type please use any convertor to convert and then play.. MKV, Divx, xdiv filetype may not be supported by many players. Bit rate has nothing to do with this, cos DVD players supports 5.1 surround sound means High bitrate Audio and Video...

Xilisoft is on of the good converter you can use.

@Ríkviðr : The question is from India, and BLDs are not penetrated in the markets that much now , i mean people rarely uses BLD and the question he asked about DVD player only not BLD :-)

I know it's possible, but I don't know how you would go about doing it and getting it to work correctly. My brother illegally downloaded Run Fatboy Run about two months before it even hit theaters, and we were able to watch it on his DVD player in perfect quality.

What that other guy said. Some Blu-Ray players may be able to play MKV, TS and M2TS and such, but not DVD players.
