After AVI Nero Burn no sound on TV DVD

Hi I am using Xp, and I have a couple of tapes that put on my computer as AVI, I am using nero and choose Video CD and burn. When I play them back on the computer everything is great, but when I put them in my standalone DVD player hooked to my TV the pict is great but no sound.

Let me say I have tried converting them to MPEG and it actually worked but lost both sound and picture quality. I have been through about 20 CD’s using different formats. any help will be appreciated.

Thanks
