Galapagos HD-DVD, US edition

Evodemux 0.628 states evo to be Frame Rate = 23.976 (24000/1001)

But when demuxed & resulting VC1 video added to TSMuxerGUI 1.7.3 shows as Frame Rate = 29.97

Obviusly there is no pulldown involded here. So what is the real situation here (one of the tools must not be correct)

Anybody can explain to me

Thanks a lot

How have you determined that there is NO pulldown applied?

When there is a pulldown in (any) VC1 stream (demuxed from EVO with Evodemuxer) and this stream is added to TSMuxerGUI 1.7.3 then it shows as Frame rate 23.976 (pulldown)

But demuxed VC1 streams from Galapagos EVOs shows as Frame Rate = 29.97 TSMuxerGUI 1.7.3

Also vc1conv shows:

vc1conv VC-1 Elementary Stream Converter 0.3
Sequence Header found
0 frames before first I-frame
Advanced Profile
Level = 3
Chroma Format = 4:2:0
Horizontal size = 1920
Vertical size = 1080
Pulldown = 1
Interlace = 1
Display Horizontal size = 1920
Display Vertical size = 1080
Aspect ratio = 1:1 (square samples)
Frame Rate = 29.970

Or am I missing something obvious?
Also (with my limited knowledge) no matter what I try with megui I can not get the correct lengh of each episode converted to h264
Each time it finished short ~ 10 min of each episode (no matter what framerate I input in the .avs script)

EDIT:
It seems to be just a bad release

The ONLY way I managed to get the right number of frames was making a conversion with vc12avi (when finished it gives the correct number)
Then the conversion can simply be deleted (as it is not needed really)

Then for 720p conversion I used megui with following script (might be not the best, but I am happy with result - playable fine on PCH)

DirectShowSource("G:\DEmuxed\EPISODE2_1_MERGED.VC-1.stream.0.vc1",fps=29.97, framecount=88052,audio=false)
#deinterlace
TDeint(mode=1,order=1,mtnmode=3,tryWeave=true)
Pulldown(0,3)

crop( 0, 0, 0, 0)

LanczosResize(1280,720) # Lanczos (Sharp)
#denoise

ConvertToYV12()
