how to enable sourcematch and/or lossless

[gheppell]

Thank you.  Another one for you.....I have a number of very large AVI files which I have created with old Hi8 tapes and/or MiniDV.  I am in the process of converting many of them to mov or mp4 using Hybrid.  However, with the largest files (some are over 10GB), I would like to cut it into smaller chunks where there are scene changes and save the resulting AVIs as original backups.  I have found a way to do this using passthrough, but the resulting AVI files always show as being progressive when the originals are interlaced.  Further, when I take the smaller, cut AVI and go to convert it to mov or mp4 using various filters and deinterlacing at that point, I always get a crash error.  

Any help would be appreciated.  thanks
