I believe ProgDVB has problem with soundcards (all other SW works great). I tried two - Audigy 2 and Realtek HD. Separately and with different drivers. No change. Tomorrow I´m gonna try whole different HW. Can you tell me yours HW setup to see where it works? Thx.

So, I tried another systems - Vista/x64, Win7/x86 and WinXP/x86. Still the same. Clean, fresh with no other soft, codecs etc.
waveoutput - sync issue starts from beginning and raise (no matter demuxer or codec)
directsound (elecard demuxer selected):
- MS DTV-Audio + any video codec, channel start ok, but after few minutes sound stops (breaks and silence in audio renderer) and picture jerks.
- AC3Filter/or ffdshow audio +
- CoreAVC, no sound from the beginning (breaks, silence)
- Cyberlink (MP2 sound), breaks and silence, jerky sound
- Cyberlink (AC3 sound), no sound from the beninning (breaks, silence)
- MS DTV-Video (MP2 or AC3), channel start ok, but after few minutes sound stops (breaks and silence in audio renderer) and picture jerks.
directsound (microsoft demuxer selected):
same, but Cyberlink and CoreAVC work like MS DTV - channel start ok, but after few minutes sound stops (breaks and silence in audio renderer) and picture jerks.
directsound (cyberlink demuxer selected): no sound and video with any selected codecs
Switching channels with elecard demuxer take long time, much longer than with MS one. I tried run it in XP SP3 compatibility mode, no change.
------------------------------------------------
Conf1 - Q6600, 8GB RAM, GA EP35-DS3R, ATI HD3870, Skystar HD2, Audigy 2, WD10EADS
Conf2 - Athlon X2 4400, 2GB RAM, ATI HD 3650, Skystar HD2, Realtek HD, WD6400AAKS
- both hooked to FSC S20-1W (1680x1050), DVI
- Catalyst 10.6 (9.9 for HD3650), SS HD2 (1.1.1.502), Realtek 2.49, Audigy (2.18.0017)
- no RAID
On both conf and every system it acts the same. Only in ProgDVB 6.xx, all other SW works great - older ProgDVB, DVBViewer, ALTDVB, DD.
Any sugestions please.

If i install a cyberlink demuxer, it will bring problems to Progdvb. Uninstall Cyberlink products and use the internal Cyberlink demuxer of Progdvb with no problems.
If you install the Dvbsupport pack, for example, don´t install the Cyberlynk demuxer, everything wil go ok.

No matter, I don´t use it in ProgDVB?
Thx for help. I unregisterred Cyberlinks PDVD10 demuxer. Now I have selected internal cyberlink (ffdshow reports "MPEG-2 Demultiplexor" using).
Cannot use default directsound - sound issues, crippled sound with every codec use.
EVR + Directsound: Speakers :
- channels with AC3 (ac3filter) are fine
- channels with AC3 (ffdshow) sync issue
- channels with MP2 (ac3filter) suffer in sound, crippled sound
- channels with MP2 (elecard) most are fine, few have crippled sound
- channels with MP2 (ffdshow) sync issue
Timeshift disabled = bigger crippling, audio delat almost 10s in just 10mins. Timeshift set to 50MB (RAM), better, but still crippled sound. ?????
Why the hell ProgDVB cannot work properly like all other DVBPlayers????

Clock problem in renderer? After few minutes it just stops adjusting rate and delay raises and raises.
