ConvertXtoDVD 5 audio problems

Just started using CovertXtoDVD 5 to convert .ts movies in HD to DVD using all default settings the background sound drowns out the voice sound so as to be undecernable yet it works just fine on SD .ts movies. I’ve tried various changes suggested by the help at Convertx but nothing works.
Any help would be appreciated----- Thanks

Did you try the new beta version ?

BETA Download

Thanks for your reply.
Yes I have the Beta Version loaded.
Perhaps I should ask if anyone has successfully used Convert X on HD .ts movie and was the audio OK and if yes did they change the audio settings?----Thanks
