I can't say. I have only tested this with VLC, which seems to report errors mostly for the transport stream (libdvbpsi) and not the video decoding itself (ffmpeg). However I am not sure about this, I am unable to draw clear conclusions from VLC debugging messages. I have recorded/dumped a few seconds for each of the two services (Astra HD Promo, Anixe HD). Playing back the files with VLC does give a slightly better result, i.e. I do get to see some frames of the video, when I wouldn't be able to see any while streaming. And it looks like Anixe HD is slightly better than Astra HD Promo, but that just may be a coincidence. However VLC crashes again eventually. Here are some of the relevant messages logged (just a sample): libdvbpsi error (PSI decoder): TS discontinuity (received 1, expected 0) for PID 0libdvbpsi error (PSI decoder): TS duplicate (received 12, expected 13) for PID 100No accelerated IMDCT transform foundlibdvbpsi error (misc PSI): Bad CRC_32 (0x055e9456) !!!libdvbpsi error (misc PSI): Bad CRC_32 (0x25f13ddd) !!![00000381] ffmpeg decoder error: more than 5 seconds of late video -> dropping frame (computer too slow ?)and then...24/06/2008 1:39:09 ΜΜ com.apple.launchd[316] ([0x0-0x1f31f3].org.videolan.vlc[5229]) Exited abnormally: Bus error I have published these short clips if you want to try them out yourself:http://www.admin.grnet.gr/pub/zmousm/astrahd.tshttp://www.admin.grnet.gr/pub/zmousm/anixehd.ts If you could suggest the necessary ffmpeg syntax, I could try it out. I seem to have trouble with both these services on this transponder, while there's at least one other report that Anixe HD is OK. So I'm wondering if it could be the case that my LNB/receiver/dish positioning combination is simply not good (sensitive?) enough for this specific transponder? Thanks,Z.
