I am trying to burn Training Day using the "getting the best out of cce" guide. In dvd2avi I played the movie and it takes 15 minutes too get to Film 95% or 10 minutes if you start counting from the moment the actual movie starts. the guide says to wait a couple minutes to see if it is film 95%. Did i wait to long? Do i use forced film or IVTC? Also how do i do IVTC?i dont see it anywhere in dvd2avi.

first of all you can never follow a guide exactly, that never works
Second:
Force film or ivtc. Sometimes force film get to 23.976fps and works well and you get no interlacing, sometimes it does not. Make a force film, ad convert it to a VFAPI avi and see if any interlacing is present. If there is, go back and change it to none, and perform ivtc on it. Use tmpeg or decomb.
The best way for you to complete an ivtc is to create an uncompressed avi of the entire movie ivtc's resized, and everything, then use cce to convert it to an mpeg. Click on my encoding guide, there is a good guide on how to do ivtc in tmpeg and avisynth, also how to make an uncompressed avi(called intermediate avi)

Clarification:

Interlacing and Telecine are 2 entirely different things.

Force FILM is one easy to use method of Inverse Telecine (IVTC). For more on Telecine, please click on this Doom9 link: Telecine Explained (http://www.doom9.org/synch.htm).

If a film starts up in NTSC and gradually increases film %, it's usually because distribution and production leaders on the DVD are video, and not telecined film. You can quickly check this by previewing the main content, moving the slider and setting the start position with the [ button. You can also examine a high motion scene frame by frame to determine if it has been Telecined.

Interlacing is when a video frame is split between 2 fields. Every other line of the image is in a different field... e.g.: lines 1 3 5 7 9... are in one field, and lines 2 4 6 8... in the other field.
You can examine a high motion scene, and if you see horizontal lines, it's interlaced.
