Problem with avisynth

[abajo]

Hi.
Some months ago a bought a new PC. I installed windows 7.
Anyway I have a problem.
If I use Avisynth for encode a video, the output file start with a black screen of 3-5 seconds.
After the 3-5 seconds, the videos is fine.
How can I remove the first 3-5 seconds of black screen on every video? I tried different settings and different avisynth version, but I can't fix this problem. In my old PC everything was working fine...

:script:
And what version of AviSynth you have installed?
Does the starting black screen appear when you preview your avs in AvsPmod or VirtualDub?
What encoder do you use? By CLI or GUI?

Hi.
As I said, I tried many version of Avisynth.

In the preview sometimes appear the black screen, sometimes not. Anyay, the black screen on the output file always appear.

I tried both, GUI and CLI.

Here's to you. Yhis is the CLI script.

"#{encbin}" --crf 16 --tune fastdecode -i 250 --fps 23.976 --sar 1:1 --index "#{prefix}#{index}.index" --seek #{startf} --frames #{lenf} -o "#{prefix}#{output}[#{startf}-#{endf}].mp4" "#{inpath}#{input}"

This is the GUI script

--crf 19.0 --preset medium --level 4.1 --merange 12 --direct auto --b-adapt 2 --trellis 2 --qcomp 0.50 --vbv-maxrate 24000 --vbv-bufsize 24000 --partitions p8x8,b8x8,i4x4,i8x8 --me umh --rc-lookahead 60 --ipratio 1.10 --pbratio 1.10 --extra:

This is the avs used by the gui.
