Winavi Divx to DVD final DVD sound stutters

[Hermit]

Winavi program is one of the best I have come across in speed and quality at that speed.
Up to now I made few DVDs with it but one problem I face in finished
DVDs is that sound breaks. Picture is great but the sounds stutters or
breaks often till the end of DVD and it is quite irritating.
Do you know any reason. May be some Problem with Direct AC3 feature
of Winavi
My amplifier display blinks as if there is no Audio input to for a brief half second picture is great
Otherwise this program is one of the best
My setting is

DVD player is JVC DR-M10
DVD Writer is LG GSA-4163B
I have observed these flaws specially only with AC3 sound 5.1 channel
Dolby the codec's are
ATSC/A-52 Dolby AC3
Number of Channels 5
Sample Rate 48000 Hz
Bit rate 448 Kbps

Are you using the latest version of WinAVI? There have been numerous AC3 bugs fixed in the last few versions.
