Might have found the issue with the info.txt missing.
If I use batch mode and have a custom filter with a UNC path to the tools folder (in this case for MDegrain) in my shared folder, then the script fail if the tools folder is missing, but Ripbot fail to see this and just continue without an error.
I did a video (Screen capture). Please have a look at it:

If GetInfo.avs is runned multiple times, then the file (info.txt) is not overwritten, but data is appended to the file.
