Hey so I am trying to burn a bunch of AVI files onto a DVD that I can watch in any old DVD player.
I have Toast and iDVD but when I try and use them to burn the files I am told that they are too big to fit on one DVD.
I have about 7 files that are each an hour long...
Can anyone help me get more than one hour-long episode on a DVD?

"any old DVD player" will not play AVI files, it has to be converted to DVD. This conversion process almost always increases the size of the video files, because MPEG-2 bitrate requires high values than XVID/etc, and most often all-in-one software assumes you want 720x480 while fills a disc with 2 hours.
Yeah, run-on sentence. Sorry.
When you let software make your choices, you'll often be disappointed by the results.
OK so what software will allow me to put all the episodes on one DVD?
Ok, let's take it back a bit as I think you might need this process broken down for you a bit:
You have 7 avi files, each at about 1 hour long.
Let say for argument's sake they clock right in at say 50mins.
You need to get these onto DVD.
iDVD only knows to encode to fill up a DVD at 2hours encoding
(worst quality) or fill it up at Best Resolution ( Highest Quality).
Toast, on the other hand works off of runtime in default.
so If you drag and drop two episodes on to the window and click
to encode, then congrats, it will do its job and put those two
onto disc using default settings.
To use Toast to get more onto a disc, you have to first figure out
how to adjust Toast to do what you want. I will use Toast 10 as
an example, but this works in any version from 7 on up.
First, get a Bitrate Calculator, I like to use this one here.
Next, figure out quality vs quantity. In other words, how
much quality can you afford to lose to get yoru video onto a disc?
for me, with each episode at about 1 hour, I shoot for 4 episodes
so using the Bitrate calc, I figure out the following :
4hrs00mins15seconds, with a defualt audio of 192kbps, gives you
a set encoding rate of 2.3mbps low end.
With Toast Open, select the Video Tab, select the DVD Tab.
At lower left, where the "Options" window resides, click "More."
When the "More" window comes up, select the "Encoding" Tab,
and enter in your information by doing the following:
You set the encoding to Custom, you set the slider to closest to 2.3mbps,
( in this case 2.5mbps) and set the high end to 5.0mbps.
Set the audio to 192kbps.
Click Ok, and then drag and drop your files into the main window.
Click burn to author and burn to DVD.
Repeat as necessary.
nice explanation, thanks...
An average bitrate of 2.5Mbps on a typical 720x480 encode is going to look like shit. The minimum bitrate for acceptable quality is 5000-5500kbps (5.0-5.5Mbps).
At 352x480, only then will 2.5Mbps be okay.
my 2 cents (I don't use Toast encoder):

I will set Motion Estimation to good (the better way will be to remove motion estimation)
The motion estimation is used to build GOP with accuracy, depending on the contents (=cuts) of the video
Without ME the GOP will always use 12 or 15 frames per GOP (and a long GOP uses a lot of B frames, the "lighter" frames)
With a best ME, the encoder can add more GOP (eg: each 3 or 6 frames), the resulting stream will use more I frames (the heaviest frames)
(end of the boring explanation )

But in runtime, 4 avis at 1hr each a lowend of 2.5mbps and a high target of 5.0 to 6.0mbps
will give him an average per of about 2.9mbps ( readjusted as I oversetimated his
avis by 10 mins each, see my post) and for a DVD-5 it will be watchable, slightly
better than Mpeg-1 but not as great as say a 2hr DVD-9 shrunk to a 2hr DVD-5
this is a case according to the OP of QUANTITY.
In this case QUANTITY is overriding QUALITY.
I think this has been made clear......

lowerend bitrate and you could actually set a better target encode that wouldn't have
to juggle QUANTITY vs QUALITY, like you can do with Compressor.
Alas, Sonic/Roxio doesn't think the average joe needs this feature........
