Using ProgDVB Pro and watching UPC package on 1°W. Now I switched to Skylink package on 23,5°E - and problem started. On many channels I get sync issues and audio distortion and video stuttering after a while. Tried all possible codec/demux combination but nothing works.

Using Cyberlink demuxer, EVR + cyberlink video decoder (MPEG2+H264), MS DTV for MP2 and AC3Filter for AC3, directsound renderer.

Compared identical channel from both packages - TV Joj:

1 - Thor 6 (0.8°W) 11766.00 V 28000 7/8
2 - Astra 3B (23.5°E) 11798.00 H 27500 3/4

Both packages use CW encryption, same MPEG2, DVB-S, cca identical bitrate, same MP2 audio, EPG. 1st one works fine, second has problems:

- directsound renderer clock stops at 48600Hz, breaks and silence raise (audio cracks) + video stutters after a while (dropping frames)
- this doesn´t happen on all channels, but many
- tried to use another MS demuxer: clock stops at 48600Hz, no breaks or silence but raising sync issue (Err)
- sometimes this corrects after few minutes, works fine few minutes but then again...
- tried another codecs (ffdshow, MS DTV, Elecard, nVidia, Arcsoft, DivX...) nothing works without audio/video problems.


Where´s the problem? Why channels on UPC work fine with Cyberlink and on Skylink not? There are also another channels (free) on other satellites which have the same problem. Thx.

Win7/x64, Skystar HD2, Q6600@3GHz, 8GB RAM, Audigy2

sync. depended from audio renderer and demux. also.

ps: Every provider have some specific in stream

So, don´t you plan to make it work in ProgDVB? If it can work in other players flawlessly (DD, DVBViewer...) why not in ProgDVB ????

Of course I plan and working on Prog demux. But I think you can fix that if read FAQ on site.

No I can´t fix it. Can and using all possible codecs/demuxer/renderer combination. This issue is present on channels in the same package even on the same transponder. Example:

1 - Markiza - Astra 3A (23.5°E) 12565.00 H 27500 2/3
2 - STV3 (Trojka) - Astra 3A (23.5°E) 12565.00 H 27500 2/3

First one works fine, second has the issue. On STV3 I have to change video codec to ffdshow, while on Markiza, cyberlink works fine. Why is that?????

Please record me 3-5 minutes samples of both channels in TS.

Here it is:

STV3 (Trojka) - issues - http://www.sendspace.com/file/mr6o3r
Markiza - no issues - http://www.sendspace.com/file/oiptm6

When I play the recorded file back in MPC-HC (Haali/internal MPEG2 or H264/AC3Filter) everything is fine.

Another problematic channel is DiscoveryHD - http://www.sendspace.com/file/ueqgi8


How it acts:
1 - When using Cyberlink demuxer: video plays normally, but audio has lot of drops, cracks, graphclock stops at 48600Hz and the err. holds at some point (often 60-150ms)



2 - When using MS demuxer: video starts to stutter after some time, framerate drops down, audio plays fine. After few minutes this goes to normal, then after few minutes again stuttering.



- AP is off in ProgDVB
- timeshift is set in memory 200MB
- for AC3 I use AC3Filter (1.63b)
- for MP2 I use MS DTV Audio
- for MPEG2 I use cyberlink (v.10)
- for H.264 I use cyberlink (MS DTV works also, but it has some bad video distortion every few minutes)

Another finding - If I disable DXVA in cyberlink, then I can use it without problems for MPEG2 channels, but picture quality suffers.

I have Q6600@3GHz, ATI HD3870, 8GB RAM, Audigy 2, Panasonic TX-P46S20E @ 50Hz
