The count of Mallu movies/mp3 in Torrent world has increased a lot when compared from previous years. But DVD Rip quality of Malayalam movies are not up to the mark.
Anyways “olathum kondu ONAM pola ” 
.
There are registered torrent tracker websites which has a good collection of mallu torrent files, but itz a pain registering and downloading from them because we have to keep the upload-download ratio and all. Some idiots upload movies of 1.25 GB size and who the hell can upload 1.25GBz for keeping the ratio 
. So itz better download from the open tracker torrent sites like mininova.org, thepiratebay.org, btjunkie.org …
