Are you sure it's correct, not the other way about? I think you make some mistakes. Try again. My data1.cab is very similar to your and data2.cab has 1.36GB

Schabik I have polish version too and it fits DVD5.

Maybe you guys try to convert updated game and this is a problem.

There is a fast and easy method to rip unnecessary sound tracks from bicks. I.e. "Previously_On.bik" has 10 of it (2 for background sound + 8 for different languages). Removing 7 of them gives approx. 15MB :)

BAMsE I'm sure that I've compressed files from original 1.0 version not 1.1 because I did it on my laptop not on the desktop computer that I play on. I've compressed both files (data1.cab and data2.cab) with the -mx -ld800 like you suggested but my files are:
data1.cab 1.5gb
data2.cab 3.0gb
I'm guessing that you hadn't left the sounds_eng.pck, sounds_eng_dlc_03.pck so your package for data2.cab is smaller.
Or there is something that you forgot to tell. Check your conversion:)
after recompressing the videos the profit is about 433mb so if you go lower with the recompression (the worst quality of the videos, believe me you don't wanna do it) you might even add the 1.01 patch.

@robysnake91, my data1.cab is 2,94GB, data2.cab is 1,34GB. If you don't believe me, here is picture:

Thanks to your conversion I have an idea how to do the conversion with original installation. :D I'm gonna do it and test it today:D

Hmm I tried rad tools but the only one audio track is tagged....I hear only the back ground music after compressing the bik ...any help please

It doesn't matter in the game sound will be ok, the voices are added by sounds_eng.pck i think so if you recompress the bik files with RAD Tools and it won't have any effect on the voices only the sound in the video will be in different quality (but it depends on your choice of sound's bitrate, sample rate, audio quality and Audio Codec you use to recompress videos).

I recompress files simply:
1. Convert with RAD Tools from *.bik to *.avi with Xvid Codec.
2. Change with program named Ultra Video Converter the size of the video from 1280x720 to 640x352, and the quality of the video and the sound to "good", frame rate of the converted video is the same as the source video, sample rate set to 44100 Hz, Audio Codec: MP3, Letter Box: Full Image, Aspect Rate: "Auto", Video Codec: "Xvid", Output Format: "Avi Xvid Format (*.avi)".
3. Convert the files recompressed with Ultra Video Converter to *.bik using RAD Tools.
4. That's All

kristy21 after recompressing biks only first track remains and other are deleted. You must extract necessary tracks from original file and put it into converted one. It's simply:

1. For this game tracks 0, 2 and 3 are "environmental" and others are for particular language. Find your one by advanced playing original file:

2. Extract tracks 0, 2, 3 and your one to wav format:

3. Mix extracted tracks to converted file (remember to mix them on correct ID):

I've compared the converted video and the original video of my own and the only change is the resolution. It has changed from 1280x720 to 640x352 so I don't think that what you BaMSE are saying is necessary.

sCHABIK how you want to convert to avi with multiple sound stream??? It's impossible without additional tools.

...only for cinematics generated by game's engine, biks have its own sound

lots of thanks BAMsE..Now I'll start the work..

it's possibile to delete foreign languages in the .bik files and leave only one? It's a question i have been for long time, and maybe it's a solution for this problem

The-revenge yes, just look at 3rd screen in my previous post. First type "-" (without quotes) instead of browsing external audio file, then point the audio stream ID you want to delete ("Mix into what Bink...") :D

BAMsE the videos that I've converted are:
ACR_MP_SEQ01_L
ACR_MP_SEQ02_C
ACR_MP_SEQ03_C
ACR_MP_SEQ04_L
ACR_MP_SEQ05_C
ACR_MP_SEQ06_C
ACR_MP_SEQ08_C
ACR_MP_SEQ09_L
ACR_MP_SEQ10_L
flashback_altair
Previously_On
previouslyon_ezio
sp_end_cgi

even when I've converted the biks in Dragon Age 2 where if I remember correctly is an audio track on each video the game worked correctly:) so I'm pretty sure that our both conversions should work

Schabik run RAD Tools and check properties ("File info") of the original and converted "Previously_On.bik". How many tracks are there? Or try to "Advanced play" both of them and choose i.e. italian lang (ID 5). Do you see the difference?

ok you were right:D I've just tested the converted video and there were no english dialogs. I've added the enviromental sounds and english dialogs.

As BAMsE says Tracks 0, 2 and 3 are enviromental and they are responsible for music and sounds of weather or something like that (i didn't check that)

And now which track is for which language:

Track 1 - English
Track 4 - French
Track 5 - Italian
Track 6 - German
Track 7 - Spanish
Track 8 - Japanese
Track 9 - Russian
