Last week i came across a tool, called ELDUMP, (EventLog Dump). This is a tool to fetch your event log entries from windows machines. You can have a look at http://www.ibt.ku.dk/jesper/ELDump/default.htm
It is very faster in fetching the entries. More over, there are lot of arguments we can pass which makes our job very simpler.
The sample format of its output is as follows,
