As JohanSWE said, there shouldn't be a problem with PCCW, as i use it fine. For DL any torrents you need a good connection speed. I think forwarding ports is going to be way too complicated to newbies at this point. An easy DL client to use is 'Torrentopia' (google it). Install it and then re-start PC. There is no spam or spyware. Once installed, go to the 'links button' at the top and choose to 'add to links' and put these addresses in the address line:
http://filelist.org
http://www.uknova.com/
http://www.fbtz.com/forum/index.php?
http://www.torrentreactor.net/
http://www.puretna.com/main.php
http://www.mininova.org/sub/1
http://www.torrentbox.com/
http://www.torrentsearch.com
These are torrent (file) sites that cover pretty much every catagory you will need. You will have to register with most of them(free), but they are totally safe and spam free. Once saved and registered to each address link, choose 'links' again and just click on one of the listed sites. With most of the things you want to DL, you will click on the name, and then choose to 'save' file to a selected drive (such as d), then it will come up with a box that gives you the option to 'open file'. Do this and it will start to DL. It may be slow at first, or even come up with an error, but leave it for a while and eventually it will start (not always but 90% of the time). The important thing to remember is that there are 2 things next to each torrent file, seeds & peers. Seeds are the ammount of people fith the 'full' file still sharing with everyone, peers are people who are still 'getting' the file from the seeds and other peers. The more seeds, the quicker the DL. So, if you see a file with 1 seed, it will take a lot longer than one with 120. Also, if having any connection trouble still, go to settings and in 'upload/limit per connection' put 80, and in 'max simultaneous transfers' put 3. The lower ammount of DLing files at one time will make it faster. Trying to DL 15 files at a time for instance makes it clog up and slow. In the advanced option in settings, try the starting port as 49333 (put if you enter this, you will probably have to okay it with your modem port), better to keep as is first. Remember, you also HAVE to share files, this means once you have finished DLing a file you should let it keep running so it can seed to others. At least untill you have 'uploaded' as much as the file took to 'Download'. If you do not share (most sites have a ratio system) they will ban you from the site. Good luck!
