I have had the same problem after updating to macOS Ventura 13.1;. I used to use every 4.0.0 (8520), which now crashes.
I^ve tried two versions of v4 (8528) but they have the same problems as 8522-8527.
I haven't tried converting an eyetv recording to an appletv but I managed to find two ways to watch recording without the skipping of the picture :
- the export function produces an mp4 files which you view with VLC, Quick Time Player or whatever
- the "EyeTV Archive" location in the preferences, - you'll list of the recordings with the suffix ".eyetv". Control-select a file shows a menu of options of c. 6 files (the names start with, for example, "00000000295905f7" - the file with a suffix of ".ts" is a MPEG-12 Transport Stream which can be opened with VLC or similar.
The second option means you don't have to export the file which may take a long time depending of the size of the recording.
I haven't been able to watch a live recording with these options.
I just hope Geniatech fix the software.
