ProgDVB SS1 Hardware mode: strange "pixelation"

Repost from "old" forum, as kindly requested from Mod).

Let me show you what happens...
Several days ago I put another HD on my pc, to start a program and data migration and remove "old" one (I hate to change PC too often).
If I start OS from old disk progdvb (started from new disk) works in hw mode, if I start the "new" OS progdvb (the same, always started from "new" disk) pixelates (but's not best description of problem). I got a shot with my phone cam to make you see the problem (bad photo, I know...)

This strange effect is visible on panning scenes, or scene changes, on static images pixels disappear.

Next, I took a snapshot of all modules loaded from Progdvb process (working and non working) using process explorer and all modules are the same except: imm32.dll, lpk.dll, MSCTFIME.IME, usp10.dll (loaded from progdvb only on "new" OS installation, they are dlls to support chinese simplified)

I looked on system resources to see if ACPI was "mapping" irqs differently but no differences.

I have a SS2 too, but HW mode is good for me, to watch tv or listen radios while working with a small "footprint" and low resources usage, so please help me too. :?

Sorry for (most probably) bad english.

hi , maybe a pci timing problem

try this :



REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SAA7146n\Parameters]
"PciLatencyTimer"=dword:000000ff



save as ´pcilatency.reg´ and doubleclick to import into the registry

Sorry I didn't say it before, it's 255 (0xff), "old" OS and "new" OS. Every key in registry is the same.
Another thing I can see is that "surface mode" image is broken (new os only).

I WAS WRONG! :oops:

Pci latency was set to 255 under HKLM\SYSTEM\CurrentControlSet\Control\Class\...\Parameters but not under driver section (I really don't know why standard installation would place pci latency there, if it's not the right place)

Thank you Silencer.

I have the same problem. I upgraded my motherboard and graphics card. I had to reinstall XP too.
The suggestion doesn't work on my PC.
Are there any more ideas. I can see lots of ghosting, it's strange. Recording works well. My dvb-s device is a nexus-s too, used in hardware mode.
New graphics card is a PCI express card, the old one was an AGP. Both are nvidia gforce cards.

Solved it by updating my motherboard's bios to the latest version.
Hopefully this will help somebody with the same problem.

TT 2.19c ?
Using (forced) software mode then, I guess...
You can find out by changing codec relevant settings. If this effects picture quality somehow, it's software mode (for the PC screen picture).
