Is there an issue with DGPulldown 25 -> 29.97 on HCenc (0.18) encoded mpeg-2 files? The reason I ask is this; I have an NTSC capture of a UK broadcast which I've restored to 25 fps. It's in anamorphic widescreen format (720x480) and I run it through HCEnc with the following switches:

profile: best
dc prec: 10
aspect ratio: 16:9
scene change: checked (all others unchecked, including pulldown, interlaced etc)
GOP length: 18 (also tried 15)

The length of the resulting m2v file is: 43:41:120
After running it through DGPulldown (1.0.9) the length increases to: 45:30:08

At first I thought it might be a GOP issue, so I tried 15 as well with the same results.

I've successfully used this procedure many times with TMPGEnc encoded files without issue. Can anyone speculate on what might be causing this?

Thanks
