[fullbohr]

I have recently downloaded a music DVD (all in proper DVD format and ready to burn) but the audio has a terrible hissing noise. now I have an audiio version of this show on CD that the quality is much better. I have already made a seperate copy of the DVD on my hard drive and have put the audio from the CDs on my comp. Just dont know how to replace it on the DVD any help would be great
any help would be great

I'll assume the new audio is the exact length and in every other way a copy of the bad audio, except for not having the hiss. This may be a big assumption. For example, DVD audio is required to be 48 kHz and yours is probably AC3 as well. CD audio is 44.1 kHz and WAV audio, so you'll have to convert it to compliant DVD audio before going any further. Also, CD versions of songs are often different than the versions on DVD (different tempo, different or repeated/non-repeated verses or instrumental interludes, etc. This project may be more difficult than you expected. Anyway, here's how you do it:

1. Demux the video out of the DVD (PGCDemux)
2. Remux, replacing the bad audio with the good (Muxman)
3. Stick the new DVD video back into the old DVD using the 'Replace' button in VobBlanker

Baldrick has a guide for doing this with subtitles, but the principle is the same when replacing audio:

Follow his Method 2 and skip the parts about creating the subs. The programs used are all free.

Music Video compilation DVDs often have the audio in WAV format, so perhaps you only have to convert the Audio CD version to 48 kHz. I use HeadAC3he for this. Load the CD version, change from 44,100 to 48 kHz, and then you should be good to go:



There still may be problems such as the ones I outlined earlier, or maybe the audio won't synch with the video (like when the lips move and the audio is either early or late). You can fix that at the same time in HeadAC3he by adding either a positive or negative delay. The delay adjustment is at the top. To find out the amount of a delay play the resulting VOB (out of Muxman) in Media Player Classic Home Cinema and use the +/- keys to adjust the delay on the fly. If necessary redo the audio and then remux.
