I cut out a 100MB sample of a standard DVB-T2 broadcast from German public television, get it here:

//EDIT//
SendSpace has become painfully slow, here is an alternative link:

It shows corrupted frames with every seek operation using DirectShow based players (which all employ LAV Filters). It plays and seeks nicely using VLC.
Using the preview in an older 32-bit StaxRip it behaves like this with different 32-bit source filters:
1. DSS2Mod with current stable LAVVideosource:
Corrupt frames
2. FFVideoSource version 2.23.1 (latest stable version by Myrsloik):
Major disaster. Preview is totally unusable. Stepping through frames not possible.
3. LWLibavVideoSource (from lsmash-r929-170224-32)
Works without problems. Seeking does not display any corrupt frames.
Frankly I have no idea what I should make out of this. If LSMASH can do it, why can't LAVVideo and FFMS2 ?
