I recently downloaded MC13.0.95 and configured it to receive and record DVB-T transmissions.
I use AC3Filter to send ac3 and dts audio to my audio receiver via SPDIF passthrough. I have tried a number of different codecs (including alternate audio codecs with spdif passthrough capability) but all seemed to suffer from the following problems. My current config uses AC3Filter and the Cyberlink video decoder that comes with PowerDVD 8. I use Windows Vista Home Premium SP1.
I am experiencing a problem with ac3 audio, SPDIF passthrough and MC13 recording files. I have experimented with various configurations with the following results:-
1. If I watch live DVB-T material without activating timeshifting, no audio problems occur. AC3Filter behaves as I would expect, sending ac3 audio via passthrough and decoding mpa audio for standard stereo output via SPDIF.
2. If I activate timeshift while watching a program with mpa audio (no SPDIF passthrough), timeshifting seems to work. If I switch to a program with ac3 audio, timeshifting continues to work and AC3Filter appears to change to use the mpa audio stream within the program that is configured to deliver deliver ac3 audio (most Australian DVB-T progams offer both mpa and ac3 audio).
3. If I activate timeshift while watching a program with ac3 audio (SPDIF passthrough), I loose the audio (picture but no audio). Changing to other mpa audio programs still delivers no audio. Audio is restored when I exit from timeshift mode.
4. If I record an ac3 audio program with MC13, when I play it back with SPDIF ac3 passthrough, there is no audio. Although AC3Filter reports normal passthrough activity (status, audio frame count etc). If I turn off ac3 passthrough in AC3Filter, audio is restored.
I am a long time user of MC. I currently use Microsoft MC in Vista to watch live DVB-T material. I would like to shift this the MC but cannot do this until timeshift playback becomes stable in my environment. If you are still with me here, thanks for reading my story. I am happy to participate in any diagnostic work that may assist in identifying the cause of this problem.
Happy new year - Well it's new year in Australa now.
