Hi Sundar, The converting software should have been part of the original kit of Canon MV920. If not, Windows XP should help you do this quite easily. If neither solution works, then you can try out some of the software options which you can buy in. Though I have not tried this personally, I think you should be able to get going with the
www.myshopping.com.au/PR--180274_Roxio_Crunch which is a versatile multimedia suite and comes equipped to handle and convert a wide range of formats. Yes, the price of the software is not the cheapest so you might want to consider long time usage before investing in this. Alternatively, you can try Canon web site to see if this software is available for free download or not.
