A little piece of advice, if you don't want your system to die sometime in the future, 256MB of RAM is the MINIMUM requirement for XP. I'm amazed that you can watch videos. So yes, get more RAM.
Is there some way in java to search for a certain element? If so, you could search for the ": " that you have in front of each data item you (I think) are looking for. Anyway, just a random idea. Have a nice day.
