Audio problems when converting avi to dvd

I was using convertXtodvd for converting all my avi's to dvd and it was great. Then about 3 months ago I started getting playback problems on my standalone dvd player. The sound 'drops' for a second or 2 at a time every now and then and it's very annoying. When I rewind and replay however, the sound plays fine. I thought it was a prob with the DVD player but it's not (this happens on other DVD players too). I also started noticing that fast forwarding and rewinding caused problems too...i.e it would jump to the next/previous chapter. I uninstalled and reinstalled etc but to no avail.
So i started using WinAvi v8 but i get the very same problem. This happens with any avi file, AC3 or otherwise. Please help this is doing my head in.
P.S a new dvd player is not an option.

 

how old is the dvd burner?? This very well looks like to be the a DVD burner problem.. try running some tests by burning other media to dvd's... otherwise you might need to purchase a new dvd burner..

 

I get the same results on both my writers. One is a Pioneer 107 which is about 3 years old and the other is a AOPEN DUW1608 which is only 6 months old. All firmware is up to date and there are no other apps running in the background. I thought it might be a codec problem but I believe both ConvertXtodvd and WinAVI use their own.

 

Try to play the file on your computer before burn and see if it is same.

 

It plays fine from the hard drive before burning. It also plays fine when watching from the dvd on the pc.

 

Have you changed discs?

 

if it plays fine in the PC from the dvd I would be looking at the type of blank media and probably trying a different kind.

 

Discs are Ritek. I've used them for years without problems.
I have converted the files on another pc, transferred the files to this pc (the one that's giving me probs) then burned to disc and it's OK, so it's something to do with this pc. It is only 6 months old.
Using the other pc all the time isn't an option though.

 

Things change rapidly with media, yesterday's Riteks are different than todays.

 

you said that if you play the DVD on your PC, it plays fine even though the sound cuts out on your tv... either its the media or your dvd player you watch them on. If the sound was cutting out on the disc, it would also cut out when watching it on your PC.
