HP DVD Play upgrade decision

Hi everyone,
Version 3.0 3602 of DVD Play came pre-installed on my Compaq Presario notebook PC when I bought it in July 2007. I do not often watch videos on my notebook and don't really a preference for one particular media player. Of course, with Windows Vista Home Premium, I have Windows Media Center.

If I open Control Panel\Programs and Features, it shows DVD Play as using only 6.8MB of space. I just discovered I can upgrade DVD Play to 3.7 v.5822. The download for this is 148MB. Wow, what a huge file to "upgrade" a program that appears to be only using 6.8MB of space.

Any of you familiar with DVD Play, from HP? What do you think of it? Would you do this upgrade?
