Barry it sure sounds like you're runnning into the FAT32 4GB size limit. Can you format at least one of your drives with NTFS (or exFAT for a USB drive)?

If drive formatting isn't the issue, it may in fact be a limitation of the PD capture module

The C: drive is NTFS, no surprise there, capturing to my desktop.
Ill try my external, and maybe install PD14 to try.
This, if I recall is only a 17 problem as it happens on my other machine.

I recall answering a question about the mp4 capture from the vc-500 where the OP stated the same problem on the then current PD20/365 that Barry brought out in 2021 in this link: https://forum.cyberlink.com/forum/posts/list/85167.page and is answered by optodata in exactly the same way.

The Op stated that he will not contact Cyberlink support as he only had a few more to do and the workaround works and is of no concern to him. I was trying to get him to write the support ticket since he has the same problem in the current PD20 version that Barry reported here for PD17. No , I won’t write a ticket for someone else that has the problem that I have no interest in pursuing. I reported the PD17 then current capture issues found and it took almost a year for most of them to get fixed.

I bet it is a simple registry hack, but maybe not so simple to me!

Registry hack or not, these problems need to be reported to Cyberlink support as forum users are not allowed to reverse engineer or hack the program. I would not ask any user to spend the time to fix it without being paid to do so.

Well...I'm very pleased to have received a reply from Support.
They reproduced the error and are escalating to troubleshoot it (my words).
Support was clear and friendly and so we shall see if they can issue a patch.
Good for them if they issue an update for an older product version. HP Envy Phoenix/4thGen i7-4770(4@3.4GHz~turbo>3.9)
