It's not really an AviSynth problem. Are you using LAV Filters to seek in HEVC-in-TS? It's a known limitation of LAV Filters to not seek to keyframes, then (because of the container not providing an index as opposed to mkv/mp4). I think with H.264 it at least mitigates the problem a bit by waiting for a keyframe which might be good enough for CRF/bitrate estimation. There's a reason people are more likely to recommend lwlibavvideosource() instead of DirectShowSource() outside of this sub-forum.
