I've not long had a PS3, I've been using it mainly for media playback. I have a Western Digital NAS drive which I managed to hack and install Twonky on - this works great and I can recommend this to anyone. I have 350GB of videos btw (I've backed-up my entire DVD collection!). The only issue is, the NAS drive was on all the time, using power, making noise etc. Also, streaming from a NAS drive causes a bit of lag, plus you don't get thumbnails for the files. Today I installed a 500GB drive into the PS3. I imported some movies and was shocked to see them imported to a single location. This was a problem as navigating this many files in a single 'folder' was near on impossible. I searched all over the internet to find a way to sort these into seperate folders (i.e. episodes of Lost in a folder called Lost). I found nothing online except people asking the same questions, but figured it out myself anyway. I'm posting this in an attempt to help others who may be searching for something similar. There probably is a site detailing this somewhere, but I couldn't find it - this site gets good search engine rankings, so is a good place to post something like this. Assuming you have copied some videos to your PS3 already, go to the videos section, highlight a video (do not select the video, just 'hover' over it) and press the triangle button. Select 'group content' and then select 'by album'. This groups things into albums, one album for each time you import - so if you imported episodes of Lost today, they will all be in an album with today's date (2008-02-05). If you import a few different times in one day, seperate albums are created and a number is added at the end (2008-02-05-2). The trick here is to import everything by group - not all at once, i.e. import all Lost episodes, then import all 24.... etc. Now the clever bit. Go to the album with episodes of Lost (again, don't go into the album, just hover over it) and press the triangle and select information. You will see info about the album, and you can then change the album name to 'Lost'. You can do this for all albums. Now - what if you copy more episodes of Lost to the PS3? They end up in a seperate folder right? Yes, but change the album name to 'Lost' and it merges the new album with the old one!! You can also change album per file. I was extremely happy when I found this out - I hope this helps a few others out too.
