AVI: Stream 1 (audio) has a non-zero start position

Hmm, in both cases the file size doesn't require OpenDML and normal avi container should be okay.
Do you get the message from your old VirtualDub version for both files? (Most folks nowdays use VirtualDub2)

When I try open file encoded as Xvid codec - old VirtualDub is freezes.
When I try open file encoded as UTvideo codec - old Virtualdub displays a message:

AVI: Stream 1 (audio) has a non-zero start position of 1152 samples (+24
ms). VirtualDub does not currently support a non-zero start time and the
stream will be interpreted as starting from zero.
