As a native speaker, and not a teacher, my reaction to both the examples you post is that there is no discernible difference in real-world usage. There may be some difference in prescribed usage in the minds of some grammarians, but if you stopped the mythical "man on the street" and he happened to be a native English speaker, I am confident that his answer would likely be the same as mine: "To all intents and purposes they mean exactly the same thing".

Dear banderas,
Thanks for your reply but i still dont get it.Here is a another example which i find difficult to understand.

I heard him say that= He said something(past simple) .(I Heard the complete action from beginning to end.
I heard him sing (from when he started until he finsihed)

heard him saying that= he was saying something (past continous) and I heard this (when he was in the process of saying something)
I hear him singing (he is singing now).
I heard him singing (I heard when he was sinbging)

Sometimes the difference is not important and you can use either.
I've never seen him playing basketball or I've never seen him lay basketball.
Both are fine.;-):-D

What would you do if you saw someone killing a cat?
If I saw someone killing a cat I would prevent it.

What would you do if you saw someone kill a cat?
If I saw someone kill a cat I would be shocked (and sad because I could not prevent it) and I would call police immediately.

When I came home I saw children sleeping. not sleep
Listen to the birds singing! not sing
The missing person was last seen walking along the High Street. not walk High Street

Sometimes the difference is not important and sometimes it is, in fact.:cheers:

Dear banderas,
Thanks for your reply. Dose your example "If I saw someone kill a cat "means that I only saw a dead (killed) cat & not the actual action of killing by some one? If yes then I think I have understood it completely.
Thank you once again for your help.

It is subtle.

By saying If I saw someone kill a cat I would be shocked , you are indicating an event that is unstoppable and unpleasant.

By saying If I saw someone killing a cat I would prevent it., you are indicating that the event is happening, but that there is a chance of stopping it.
