I put together a dvd using a no. of avi clips including divX clip & the total length was 186 mins. I burnt it with menus & at high quality. No problems. Which astounds me why you can't get yours to work. Yours is only 101 mins.

You could try saving it as a disk image & then burning as an image file. Load the video, then hold apple & D keys. Then after video conversions & image file creation, you would go to Copy tab, select advanced button & select Disk Image. Then load the disk image & burn. Make sure the image file is 4.37 GB or less in size!!!

If you haven't already, update to Toast 6.0.9 there's some bug fixes & an improvement in the video conversion codecs used.
By the way I used to use TDK but found they're not as reliable as Verbatim.

Well now that is strange....
I dont really know how to proceede.... have upgraded to 6.09.
Would love to know step by step how you did it?
What about compression?

Try the technique I suggested.
1. Select video format as you normally would.
2. Put the video in (drag & drop or using the Add button.)
3. Select DVD-Video as output in advanced window. Select Pal or Ntsc as required.
4. Hold down both apple & D keys (or go to file menu & select Save as Disc Image.
5. Then wait for the conversion & disk image creation.
6. Go to finder & look at size of file.
7. In Toast press Copy tab & in advanced window select Image File. Drag & drop or press select to find your image file.
8. Put disk in & press burn button.

Toast makes its own calculations on any necessary conversions from avi to mpeg2 & any settings you've made.

Compression? An avi is generally already compressed. You said your avi is 701.2 MB & runs for 101 mins. That is already highly compressed. Toast will try to make full use of the space on the dvd. So the more you fit onto the dvd the lesser the quality. (If you already have an mpeg 2 file though that's apparently a different kettle of fish.)

Tryin it now.... I'll let you know how i get on....

Thanks for all the help

Well now,
all worked fine until about half way through burn, and I got this message:
The drive reported an error:

Sense Key = ILLEGAL REQUEST
Sense Code = 0x30, 0x05
CANNOT WRITE MEDIUM - INCOMPATIBLE FORMAT

What do you think?

No comprendo...
If the file is too big, it's not gonna fit on one DVD. If you want to compress it, then you'll decrease it's quality. Do you really want that?
How big is the file?
How do you go about it when trying to make a DVD with Roxio?

fai un dvd-rom

I didn't realise you had double-posted. Bad media is the sounds of it. I recently had a bad disk & returned it for a replacement. Everytime I put the same disk in it would refuse to be read by any burner softw. The TOC is unreadable basically. You get bad batches of CD & DVD media. If it's not the media then either your burner is not compatible with the media or your burner needs a firmware update. You didn't actually tell me which brand or model burner you have. Apple have used different brands of Superdrive.

So what size was the disk image by the way. It needs to be 4.37 GB or smaller. Verbatim disks will sometimes fit 4.38 on but TDK won't! Pity you don't have a dvd-rw burner. It might save some disks.

Try to burn your disk image at single speed & don't use any heavy programs during the process. Also set Toast to Buffer Underrun Protection after you press the burn button. As the series of images below show:

Using the process above, Toast converts the video before creating the disk image. Then after image is created you can burn & select advanced options as below (good idea to close & re-open Toast before you do this!) Burn at a slow speed like 1x for guarantees of a reliable burn.
