uninstall 2.5.7 / install 2.5.6

[EuropeanMan]

If I am running a Megui 2CD conversion from DVD9 files right now (still many hours left on it)...Can I uninstall AVISynth 2.5.7 and reinstall 2.5.6a?

Or should I wait til MeGui is finished?

EuropeanMan: If megui is using avisynth (if you has opened an avs file) you need to wait until megui is finished and closed done because avisynth.dll can't be overwritten/deleted while in use. (But why do you need to downgrade?).

I am currently using 3 filters in my 2CD rip process within MeGui...it is on the 2nd of 2-passes. 18 hours left on that run...yes, my computer is a bit slow these days...so I do NOT know if MeGui is using AVISYNTH right now?...

But I guess it's safe to assume it is? Or how can I check that?...through Task Manager?

As for downgrading...the reason is here: (towards the bottom of the posts)

It is using avisynth in that case. So you will have to wait.
(BTW if you have enough disk space it might be a good idea to save the file you are encoding to a lossless format like Huffyuy or high quality mjpeg before encoding to the final format if you're using slow filters and use the lossless file for the multipass encoding so you don't have to run the slow filters more than one time)

@EuropeanMan,

Please explain (in this thread) your problem with 2.5.7 versus 2.5.6!

I did fix some boundary problems with the resizer core which occassionally effected the bottom and/or right hand edge of an image. (The pixels where sometimes darker than they should have been.)

I think it is this problem EuropeanMan is expericing with 2.5.7:
Phase I, PREPARATION started.
- DVD-RB v1.20.4
- AVISYNTH 2.5.7.0
- CCE 1.0.0.4 encoder selected.
- AVS Filters are enabled.
- "Steal Space from Extras" mode (10%) is enabled.
- Source: GADAR_DOLBY_SCN
- VTS_01: 3,723,406 sectors.
-- Scanning and writing .D2V & .AVS files
-- Processed 320,907 frames.
-- Building .AVS and .ECL files
- Reduction Level for DVD-5: 44.1%
- Overall Bitrate : 2,298/1,839Kbs
- Space for Video : 3,004,012KB
- HIGH/LOW/TYPICAL Bitrates: 1,920/1,694/1,839 Kbs
[06:11:13] Phase I, PREPARATION completed in 9 minutes.
[06:11:13] Phase II ENCODING startedIt's possible that Avisynth could be the cause of undersizing...I've seen other say they are getting undersizing with ver 2.5.7.... and when going back to the ver that comes with DVD-RB (2.5.6.) the undersizing goes away.

I've also seen the under sizing be fixed by adding "CCEAQM=1" into the rebuilder.ini under [Options]

[Options]
Mode=1
OneClick=0
ReduceOpt=0
NoWarn=1
AdditionalOutput=1
CCEAQM=1
LogFile=1
QuEncHQ=1
EncoderMinimized=0

with this option on do 3 passes and you should hit your target sizing (after going back to AVISYNTH 2.5.6)
using this script in DVD-RB
