How to decode packet data capture?

[Shockwave]

Ok, lets say I set up a packet sniffer on my network (Which I have) How would I actually go about decoding the data. It displays the data within the packet as..
03 4f 32 g1 4h 55 32
34 h4 2j.......
Thats just an example I made up real quick, but my question is...What is it? And how can I turn that information into what is actually IN the packet, such as text Like "This is the text in the data" or what not. Or is there any way to decode it?
Thanks!

********UPDATE***********

Ok, I figured out that its Hex, and I have also figured out how to convert hex to decimal. But, how do I change THIS into something that makes sense to a human!?

Most sniffer programs decode it for you. Yours doesn't?

I'm not sure...Here is an actual capture...
0x0000 00 E0 34 F1 88 54 00 60-97 2C F5 5F 08 00 45 00 .à4ñ?T.`?,õ_..E.

0x0030 20 00 3C 6B 00 00 02 04-05 B4 01 01 04 02 .<k.....´....

Is the stuff on the very right the decoded version?

I think there are free programs (developed by university)
to decode these data (I have seen one, but can't remember
the name). The one that I have seen decode these packets,
IP headers, and the data.
Or you can decode them yourself, just find out how these
packets are layout. Usually the first 8x32 bits are the
headers, not sure though.
If you are using Windows, check a program called Windump
and read the manual for how to decode these packets.
