In that case, I do not recommend to you scripts such as Invision or the other file sharing scripts around, you don't need them!
Unfortunately, mIRC doesn't differentiate between the latets movie blockbuster and a video of your son. Obviously, that's not to say it should be impossible to get the file as other people manage it..however, it is a strange issue and other than what has been said in other threads (you might also use 'hang up' as a search term) that's the only thing I can think of.
If you have a firewall/router or you're DCCing from work (network) then that me be causing the issue. If feasible, try disabling the former for the short period of time that you get the file. Alternatively, speak to your wife on IRC and guide her through compressing the file.
G'luck
