I have a wee problemo....

Im converting old VHS Tapes to DVD via a Philips combi unit. After burning them, I tested them they worked fine on the unit.
I put the disk in my pc to burn the new DVD onto my pc and it is saying its a CDA file. I googled it and its a audio file so i looked for a CDA convertor online but the only ones i can find are ones that convert to other forms of Audio file.
I know i havnt just recorded the audio of the videos as it works with video and audio on the player.
Is there a setting i should be changing or is there a convertor that will convert from CDA to a video and audio file.


As i said...confuzzled!
Thanks in advance!
