A friend of mine burned for me a couple of videos to this CD.he used Ashampoo burning studio on his Pc and selected the "burn to CD/DVD" option,the videos where in ".FLV" format

Afterwards i tried to play the disc on my dvd player(Tedelex Te2003) but it said 'bad disc'.what should i do? Is the problem with the .Flv format,is it not supported on Dvd players? Or should the cd be burned differently like to vcd or something? Please help ^^
