Frames are lost or not displayed when fast backward

[ap-520]

Good day everyone.
Please help me with this problem.

In VirtualDub2 44282, frames are lost or not displayed when fast backward and pref frame. During normal playback, then everything is fine.
System: Windows 10 64 bit 1909 / Intel UHD 630
Virtualdub2 44282 /
Source file is MPEG2-TS
Video Codec: H264/368x294/8.00fps/200kb/s bitrate/
Audio: MP3 128kb/sec/48000Hz/stereo/

My steps to solve:
1. Video - enable full prossecing mode
2. Option - Performance options - chahged to max value
3. If convert source file to AVI with Xvid than is OK.

Did you try disabling "Drop frames when seeking" under Options?
