Sonic will not finalise

I have been using sonic digital media studio v7 which came on laptop to burn a home movie to dvd. DVD did burn to dvd-r but will not finalise the disc and therefore cannot be played on my panasonic dvd player. muvee producer worked fine and burnt to dvd-r.

Any thoughts or ideas would be great

You don’t have it set to record a multi session disc do you? Check this first.

No it is only set one session.

Have installed Nero express to burn from but this device says that it will not copy mpeg, wma etc only video dvd files. No compatible files are found.

Any ideas at all.

Nero VisionExpress will convert to dvd files from most formats. Try that instead.
