perhaps someone could help me with my problem. I have tried to google and talk to some of my friends, but no luck finding the real solution. I use Toast 12 Titanium (v. 12.1). My post could be a bit longer, but I want to give most of the details of this case.
Part 1 = I have several AVI files that I tried to encode/burn to BD-R to my personal use. With several, I mean over 70 (tv episodes which are not officially released anywhere, sadly). I chose "automatic" encoding and "best", so encoding took several days (I have a very old Macbook so that's one reason why, I'm sure). I read from these forums that Toast SHOULD preserve the aspect ratio of the source file (which in this case was 4:3) when choosing "automatic".
Well, after successfully burning the disc (sure, I had to remove some episodes and re-multiplex a couple of times but that was pretty easy since Toast had the "converted items" files) the actual video looked relatively good on BD-R (considering the source file) and sound was there. BUT: the original 4:3 aspect ratio was horizontally stretched to 16:9.
Part 2 = I tried to do the project again, but this time choosing "custom" (and "best" again) setting for encoding so that I could actually choose "4:3" from the menu. Downside was that this time I also had to choose the bitrate-settings which can be a bit tricky for a person like me (and I really couldn't crank the bitrate anyway, since there were so many episodes and the original bitrate in these avi-files wasn't very high). Well again the encoding took some time and this time the video looked worse - more pixelation and such at least - and the original 4:3 aspect ratio was AGAIN horizontally stretched to 16:9 (even when I clearly chose 4:3 from the custom menu). At this point I was puzzled.
Part 3 = Now I, at least, tried to burn a data disc (Mac/PC) so that I could watch the avi-episodes "straight" from PS3. But another set-back was that PS3 said that these files are not supported. So these may be avi, but perhaps not in the most conventional format (since PS3 should support some AVI-files).
Here are the specs of the first file (the other files seems to be pretty identical, but bitrates/size can vary a bit) - info from VideoSpec:
