Funny sound problem when converting...

[andyg]

I bet no one can tell me why this is happening:

My system is an Athlon XP1800+ on an AN11 motherboard with 512MB Ram and am running Windows 98.

Am trying to convert video files to MPEG to burn to disk. Which I have done succesfully in the past. Have had a few probs here and there but have managed to sort them and am producing VCD's with excellent picture quality now.

My problem seems to be the sound at the moment. Am using TMPGEnc with the Directshow multimedia file loader set in Environmental as high priority and am using highest quality setting to do my encoding.

When played on my DVD player, the sound 'drops out' every-so-often, only for a second, and then comes back again. The sound remains in sync with the video. It's as if someone has pressed 'Mute' for a second.

At first I thought it was my DVD player that was at fault but what I have now noticed is that whenever there is a 'mute' when played back on my DVD player, on the resulting mpeg, there is a loud 'noise' on the sound channel. As a result, I think my DVD player must have some sort of sound filter in it and instead of playing the sound, it mutes the sound output for a second.

On inspection of the original avi, there is no 'loud' noise on the sound channel. This is being artificially added by my PC whilst converting. Anybody got any clues as to what could be causing this 'interference'? TIA

Before you encode,do you extract the audio as a WAV ?
