*** glibc detected *** sidecar: double free or corruption (fasttop): 0x093c6f40 *** media/video-hd2/To Process/The World at War 02 (BBC iPlayer).ts

I repeated the sidecar generation from the command line. Compared to a native TS file, fast forwarding and rewinding is less smooth at speeds >x8, but it still works and normal playback is fine.ĮDIT. The HMT file created had identical recording start and finish times so I manually edited this. The file extension was renamed 'TS' and the sidecar files were created on the HDR-FOX using the sidecar package. An mp4 file (h264/ aac) was converted to m2ts with TSMuxer GUI. The playback issue was not related to the sidecars, the naked TS was similarly jerky on the HDR-FOX but played OK on a laptop and on an Android Tablet streamed over WiFi. This worked, but the TS file did not play smoothly on the HDR-FOX. The most successful involved creating an m2ts file from the mp4 with TSmuxer, then transcoding the audio to AC3 with AVIdemux. I tried a few things to create files for processing by AV2HDR-T2, but avoided transcoding the video stream. This was partially successful: the file played but without audio. The Foxsat edition (I think it was version 3) of AV2HDR could process the m2ts file, so I took the TS file produced this way and reprocessed it ith AV2HDR-T2. I initially tried AV2HDR-T2 (Win7 PC), after remuxing to m2ts with TSmuxer GUI, but the file could not be processed. In case it is useful, I had a couple of mp4 files (h264 video, aac audio) I wanted to convert to TS with sidecars.

The file played fine on the HDR-FOX (when renamed '.TS') but, as indicated by Raydon, the sidecar package could not create an NTS file. This successfully created an m2ts file from the mp4 file. I tried the command in post 2 (I added '-acodec copy' to make sure the audio was copied too).
