freeware conversion software query

[starrylizard]

 Hi 

My computer has died a horrific death and I'm attempting to set up my laptop to be able to vid after quite a long hiatus.  I used to use a freeware program to convert files into high quality WMV files that then worked in Vegas. Would anyone know what program it was?  Or if you can offer a decent alternative method, that too would be useful.  

Thank you heaps
