Video but no audio when played on other machines

Question

iMovie to iDVd. Burns OK, plays on iMac as it should, but then when checked on other stand alone machines - video fine, but no audio at all.
No problems up until recently. Checked settings - seem to be the same.
Using PAL settings. Burning to DVD - R.
Any suggestions about where to start checking appreciated.

Hi Kaik and welcome
Is this an iDVD6 project that you currently have on
your computer now? If so, please try burning a disc
image to the desktop from the file menu within
iDVD6.
Click Here
Then test the image with Apple's DVD Player
application. If it plays exactly as expected within
this DVD Player application then the issue is with
the media, your burn speed, and/or the set top DVD
Player and not iDVD6.
You can lower the burn speed in Roxio Toast like
this:
or if you prefer use Apple's Disc Utilities and lower
the burn speed there like this:
Hope this process of elimination makes some sense but
if not please feel free to ask further questions.
Good luck!
Thanks SDMacuser for your prompt response to my question.
Working through your suggestions and trying to isolate where the problem may lie. Mention of a Disk image was something I had never tried, and very useful for future reference, once this problem is solved.
Haven't got the latest version of "Toast" so will purchase that. Tried a separate Sony standalone DVD player. Video and sound there, but not on the Sony DVD hard drive recorder nor on familes back in NZ. Very strange. Will keep on working through your other suggestions.
Liviing on a small rock in the Pacific and being abe to source help such as yours via internet is very much appreciated. Thank you for your time and expertise. Will be back in touch. Cheers,Keith
