I just spent my time submitting and downloading a clip via eathalo. After downloading the four parts and putting them together, I could watch 1 minute 50 seconds a wall. A wall in HD! congratulations. They even want money for HD and making the timebar disappear. And I got a f***ing clip of a wall! Seriously, do not use this junk.
I am not really sure what other websites translate Halo 3 film clips into a form where you can download and view them on your computer. My only choice would be to use eathalo unless you know of other ones.
I've used eatHalo a lot, and have never had a problem with them. It may be an isolated incident; perhaps you should post a comment on his bnet page or PM him and he'll probably look into it.
halochiefs.net is what I use, u just have to post 10 times then they take 4 vids at a time... it usually takes 1 - 2 days for 4 vids! U can only make one request at a time and the total video can only be 3:30, but still it's really good quality and u can dld it right to ur computer
