What would produce the best audio possible out of these settings?
Output frame rate:
Frame rate of the output video file. 25 (PAL) or 23.97,29.97 (NTSC).
Warning: this value is not automaticaly set, if you choose a different frame rate from the input, a pull down will be performed. Avoid conversion between NTSC and PAL.
Default is : 25
Detect 24Fps:
Detect automaticaly 24Hz progressive NTSC.
Default is : Yes
Force 24Fps:
Force input to be a 24Hz progressive NTSC.
This flag works only if detect 24fps is checked. (Use it if you think that the 24Hz detection doesn't work).
Default is : No
Dolby suround:
Enable dolby suround downmix.
Allow to preserve better 5.1 FX in stereo mode
Default is: Enabled
Audio 48KHz to 44.1 KHz:
48KHz downsampling mode.
0 : Normal mode (fastest)
1 : High quality (slower)
2 : Export AC3
Export the source AC3 to a file, you can afterward select the output file by clicking on the Select AC3 Output button.
3 : 44.1KHz (no conversion)
Select this when you don't want to make sound conversion when you have a 44.1KHz source stream.
4 : 48.0KHz (no conversion)
Same purpose as choice 3, when the input frequency is not specified (A3,LPCM) it is usualy 48KHz
Default is : 0
Volume:
Gain of the audio output.
No normalization is performed. A value of 1 can't generate distorsion (cracking) but the output sound may be very low. The default gives a good volume for most DVDs.
Make few clip of the movie where you know the volume is high and adjust this value in order to get a good volume. You can also use the sound normalizer to find an otimun volume.
Default is : 3
Save your DVD drive:
Create a temporary buffer to avoid the drive to be switched on/off too much.
If you use a RAM buffer you may disable virtual memory to get more speed. The file will be write in your Windows temporary directory (TMP environement variable).
Default is : Size: 10MB, Location: RAM
DeMacroVision:
Remove macro vision protection from the movie.
Default is : Yes
Key Search:
Mode for CSS key search (the mode 0 works fine in 99% of cases).
0 - Search a key one time when starting
1 - Search a new key at each VOB-ID
2 - Search a new key at each CELL-ID
3 - Search a new key at each VOB/CELL-ID combination
4 - Disabled
Default is : 0
iDCT:
Inversce Discrete Cosine Transform routines (include also motion compensation)
MMX is fast and suitable for most CPUs. FPU give the best quality.
Default is : Auto detected
Overlap:
Go backward of specified amout of time when output volume size has been reached. (This has no effect in custom chapter splitting) i.e. Overlap=10 if the volume end at 1:10:25 next volume will start at 1:10:15.
Default is : 0 sec
Audio Video Synchronisation:
Resynchronise video and audio periodicaly. (not always necessary)
Default is : No
Deinterlace Filter:
Use this when your image is interlaced (when 1 line / 2 is shifted)
Warning: if you set odd or even field you cannot be sure that it is the good field, Just make a clip of 10 images to see if you're right. Interpolate mode interpolate the even field (you lose a bit quality for SVCD but it always works)
Default is : None
Output frame rate:

Warning: this value is not automaticaly set, if you choose a different frame rate from the input, a pull down will be performed. Avoid conversion between NTSC and PAL.
