A great combo is
www.newzbin.com and usenetserver. newzbin allows you to just click on a particular d/l and it takes the message id (which inc.s all the necessary files) it then d/s in your reader (using grabit, which is amazing for speed) and its then just a case of unrarring, htdtv-mpeg conversion and if necessary quickpar.
Im with bulldog on a 8meg connection. getting average speeds of 550kbps d/ls on most hdtv sources (this is running 4 simultaneous files into the reader at max). This means i can have a full dvd size file in 3 hours. Or a .ts hdtv film in 6-8. I just have a browse on newzbin each morning before work and load it in. Then each night i can just unpack and clean it up and enjoy the HD movie on my 42" pd7200 and dd5.1 from the denon and kef 5005 combo. BLISS!! Something always to look forward to after work.
Some great movies to look out for at the moment - Ray 1080idd5.1, Gladiator bev 1080idts, the forgotten 1080idd5.1, spartan 1080idd5.1 lord of the rings hdtv, alias hdtv, bones hdtv, us open hdtv, longest yard dvd.
