Editing After Effects interpretation rules file

I am getting increasingly frustrated having to constantly change the interpretation of imported footage and I want to edit the default interpretation settings that are applied.
I understand that I have the edit the active "interpretation rules 802.txt" file but I am unsure of the exact changes that I have to make.
Does anyone know how to change the default settings to..
Pixel aspect ration: D1/DV PAL Widescreen
Seperate fields: Upper field
or even better reply to this post with an exact copy of the complete interpretation rules text based on my existing file which I have copied to the bottom of this post..
Thanks
(my existing text file is pasted below)
# "Interpretation Rules.txt"
# Adobe After Effects Automatic Footage Interpretation
#
# lines beginning with "#" are comments
#
# basic format of a hard rule: {match requirements} = {set interpretation}
# basic format of a soft rule: {match requirements} ~ {set interpretation}
#
# + for each rule that matches, the interpretation is set; wild-cards ("*") allowed
# on both sides; wildcard match matches anything, wildcard set sets nothing
# + multiple rules are allowed to match, later matches override earlier matches
# + all rules are scanned in order, one rule per line
# + rules are applied after pixel aspect ratio, alpha information, and field label
# information is read from a file
#
# + soft rules will not override values that are specified explicitly by the file format
#
# width, height, frame-rate, file-type, codec =
# pixel aspect ratio/name, field order, conform frame-rate, alpha interp, icc profile code or profile description (one or the other), linear light
#
# width & height are integer numbers
# frame-rate is a decimal number
# file-type is four characters in quotes (4c's)
# codec (applicable for QT & AVI only) is also 4c's
#
# to find out the file-type and/or codec 4c's for a specific type of footage,
# opt-click (Mac) or alt-click (Windows) on the footage in the project window;
# the 4c codes will appear in the last line of text by the thumbnail
#
# the pixel aspect ratio is a ratio of integers (e.g. 10/11)
# optionally followed by a name for that ratio (e.g. 10/11/"My Aspect")
# the field order is a single character, (F=frame, U=upper field, or L=lower field)
# the conform frame-rate is a decimal number
# alpha interp: (I=ignore, S=straight, P=premul/black, W=premul/white)
# alpha interp is ignored for footage without an alpha channel
#
# icc profile is specified either by profile code which is four characters in quotes or by profile description which is a string in quotes with at most 255 characters plus quotes
# The supported profile codes are:
# - working space profile: "wRGB"
# - embedded profile: "embe"
# - preserve RGB: "pRGB" (this does exactly what Preserve RGB checkbox does in Interpret Footage dialog)
# - sRGB: "sRGB"
# - Adobe RGB: "AS98"
# - Kodak 5218 film profile: "ginp"
# - SDTV NTSC: "r6nf" (SMPTE RP 145 primaries and ITU-R Rec. 709 TRCs. Black is encoded at 0 and White is encoded at 1.)
# - SDTV NTSC 16-235: "r6ns" (SMPTE RP 145 primaries and ITU-R Rec. 709 TRCs. Black is encoded at 16/255 and White is encoded at 235/255.)
# - SDTV PAL: "r6pf" (EBU Tech. 3213 primaries and ITU-R Rec. 709 TRCs. Black is encoded at 0 and White is encoded at 1.)
# - SDTV PAL 16-235: "r6ps" (EBU Tech. 3213 primaries and ITU-R Rec. 709 TRCs. Black is encoded at 16/255 and White is encoded at 235/255.)
# - HDTV (Rec. 709): "r7hf" (ITU-R Rec. 709 primaries and TRCs. Black is encoded at 0 and White is encoded at 1.)
# - HDTV (Rec. 709) 16-235: "r7hs" (ITU-R Rec. 709 primaries and TRCs. Black is encoded at 16/255 and White is encoded at 235/255.)
#
# The profile description can be looked up either in UI (project window thumbnail info) or in a color utility such as ColorSync or it is user-defined
# when creating a custom profile
#
# linear light is an integer (0=Off, 1=On, 2=On for 32 bpc footage)

I edited this file once back in AE3. My machine never worked the same.
You will want to work on a copy of this file and you will want to make sure you spell everything correctly (separate not seperate and ratio not ration) so use a good text editor and then cut and paste after spellchecking.
Before diving into this, search the online help carefully and then cruise blogs at adobe.com. Start with the after effects forum from this portal:
