SNL Season 1 Disc 1 (NTSC) Was ripped with anydvd 6.0.2.5 and dvd decryptor. Encoded with dvd-rb PRO 1.21 Using CCE SP2 1.00.00.13. The source Appears to Interlaced and Bottom Field first. Also used the following filters on the first try:

ConvertToYUY2(interlaced=true)
SeparateFields()
odd = SelectOdd.Convolution3D(0, 6, 10, 6, 8, 2.8, 0)
evn = SelectEven.Convolution3D(0, 6, 10, 6, 8, 2.8, 0)
odd = odd.Undot()
evn = evn.Undot()
Interleave(evn,odd)
Weave()

Encoded this disc twice and the finished image plays with jerky motion consistent with incorrect field order. At first I used to use the following settings; check top field first (equal to 1) and have the offset line=1, but then changed that to uncheck top field first (=0) and offset line=0.
Loaded the ecl created with rebuilder using CCE SP 2 and noticed that all of the segments had top field first Unchecked and offset line set to 0.

I guess I have 3 Main questions:
1) Does Changing settings other than the timecode effect rebuilder, because it seems to set everything the way it wants it regardless of what you choose (I am only concerned with top field first and offset line)?
2) What should be the correct settings for encoding an interlaced bottom field first source? I am assuming you check top field first and leave offset line 0.
3) If for any reason you want to alter the ecl rebuilder made with CCE SP 2 how do you do that? I noticed that rebuilder sets all of this disc to unchecked top field first and offset line=0. I loaded the ECL, checked all the top field first boxes and then saved the ECL. But when I started to encode I got an error sub script out of range. I'm thinking that I have to alter the rebuilder.inf but I don't know What entry to switch.

Any help would be Greatly appreciated

First I would remove the filters and see if they are the source of the problem...

Second... be careful with CCE and field order. It changes from version to version and doesn't work exactly like you think it might. For example, in some versions a BFF stream will be shifted up one line and become TFF on output...
