Sound Problem After Convert wtv - dvr-ms

hi
i have half recorded a tv series in win 7 media center
i have converted the first two files so i can import into dvd author 4 Latest Legal Version to edit out the adverts the first file has good sound the second has no sound at all see below for some reason the audio layer has changed it seems ??
this is what it says after i have converted and imported into dvd author has anyone else had this problem can anyone advise please this is a freeview uk tv chanel that was recorded TIA for any advice you can give me
PS
this has happened a couple of times at first i put it down to bad recording

First File Sound Great
Video Mpeg 2 Video,704x576 25fps Picture ratio : 16:9,PAL
Audio Mpeg 1 Audio Layer II, 48000 Hz, Stereo, 128 kb/s

Second File No Sound
Video Mpeg 2 Video,704x576 25fps Picture ratio : 16:9,PAL
Audio Mpeg 1 Audio Layer II, 48000 Hz, Monaural, 64 kb/s

In 'Speaker Properties' in the 'Advanced' tab, change the 'Default' format to match (48 MHz ??) using the pull down menu - have all sound apps closed when doing so.

BTW, the files may be protected by their copyright owners and if so this may be ocurring to thwart copying of Premium TV Shows or DVD Movies.

i get what you are saying but these files are a series of recordings from the same tv chan series 1 - 6 play perfect in wtv format and all i have done is convert from wtv to msdrv as per the convert tab nothing else weird

what are the formats you are working with and what is the format you want as end result?

hi
ok here goes
i am recording live tv in win 7 media center which are recorded into aWTV files if you then right hand click the file win 7 gives you the option to change into a DVR-MS file i then import these into TempEnc 4 dvd author to remove adverts and burn to a dvd what happend was the first file had sound and the second did not on investigation i noticed that the audio had changed see below

First File Sound Great
Video Mpeg 2 Video,704x576 25fps Picture ratio : 16:9,PAL
Audio Mpeg 1 Audio Layer II, 48000 Hz, Stereo, 128 kb/s

Second File No Sound
Video Mpeg 2 Video,704x576 25fps Picture ratio : 16:9,PAL
Audio Mpeg 1 Audio Layer II, 48000 Hz, Monaural, 64 kb/s

i am trying to find out how and why this happened it has happened before i put it down to a bad recording at first but the two files listed were from the same station episode one and episode two

hope that is what you are wanting to know dvd author can't handle wtv at this present time

Sounds like an incompatibility issue with one of your programs. The people at hack7mc.com have a guide that should give you a step by step for converting. I hope this helps you out. Here's a link for you.

hello peeps Tiss me again
my problem has reared its ugly head again after converting wtv to dvr-ms recorded tv i loose the sound = audio
VideoReDo reports no audio stream present i thought i had curred this but obviously not anyone have any ideas
i was blaming the digital switchover my tv card is a TBS 6280 if that helps
thanks for any thoughts dont fancy a complete reinstall at this time of life

hi peeps
update done a roll back too last week and now all is well so far
all the recorded files now have the audio stream showing and working
very strange i have not installed any new programs for ages just the normal updates for win 7
full scan with microsoft showed no infections etc so i guess its another spook in the system

I was able to solve this combining some switches for ffmpeg from various sources.
...\ffmpeg -y -threads 8 -i inputfile.wtv -target pal-dvd -deinterlace -async 48000 output file.mpg
