Every 4th frame is repeated (ie. 1,2,3,4,1,5,6,7,8,5...)

In am encoding a DVB (satellite) source MPEG-2 file, 4:3, 29.97 fps, Progressive... it is 1970's sports film.

I use TMPGenc Plus 2.58.44.152 to encode the file through an avisynth filter and .d2v (dvd2avi) project file.

I have made many successful DVDs in this method, but this particular film has a problem in 10-to-20-minute chunks where a frame will be duplicated 4 frames later (ie. 1,2,3,4,1,5,6,7,8,5,9,10...) making a jerky/flickered playback. The rest of the file is fine.

I've tried setting my de-interlace filter to true, false, and removed it completely; I also tried setting Top Field First instead of the usual Bottom; none of these worked.

The source material is ok, scanning it through dvd2avi is also fine, but through TMPGenc it is not. Scanning the frames in TMPGenc - MPEG Setting/GOP Structure/"Force picture type setting" shows the problem before encoding.

Using the avisynth file below, the problem was as described above. Using the D2V file directly showed a similar problem but in this case it was as if a half-interlaced frame was coped in 4 frames later (presumably the avisynth filter fixes the de-interlaced part by copying the rest of the frame forward, or something like that).

If anyone has any ideas about this or has encountered this problem before, I'd appreciate your help.

Thanks.

Here's the avisynth filter (though the problem still occurs without it) :

movie="1975.d2v"
MPEG2Source(movie)
FieldDeinterlace(blend=false)
GripCrop(352,480)
GripSize(resizer="BicubicResize")
GripBorders()
converttoyuy2()

ive had this problem b4 and i found a weird fix also if you goto mpeg tools and de-multiplex then take the output video to the merge and cut and cut 15 sec from the video and let it run it will rewrite the header and it normaly fixes this. ive had this problem pulling video from my dish dvdr but it doesent always work if you find a better way please post ^^and i hope this works for you.:D
