I've tried it, but it didn't change the outcome.... the video is still choppy at points and it's like the video codec jumps ahead in time, leaving behind 1-2 seconds of video... then it must stop and re-buffer.

I don't know what to do.

Try uninstall of the new DDSOURCE.AX
It uses the same CLSID as the 1.3 version.
Maybe your system will take the 1.4-version first when you start 1.3 ?!

Thanks, will try it ... but... when you uninstall DD, doesn't it unregister and remove ddsource.ax?

I will not format my PC ... my windows setup is many months old and I format only coz sometimes i change critical hardware components... I know how to manage a windows install, and everythjing works fine for me now. The maximum i'll go is to reinstall the nvidia codec, even if it currently works cor...

The problem is, i've reinstalled 1.3c but i have similar problems.... no more choppy playback in some channels.... but lags, stutters and occasional lockups in ALL channels

And trust me it's not a receiver problem or a codec problem.... i changed nothing, just installed DD 1.4

1) "Reset DS on channel change" must be active. (default setting) yes, but ... when it's active, it takes forever to change channels... it's this that made me switch from progdvb to dd! and btw v1.3c worked well with this option off... 2) Some codecs might not work fine with new source filter (ddso...

I just verified: the memory allocation increments steadly while on choppy channels, and after a certain limit freezes the program... i've waited for it to take 80mb of RAM.

While watching working channels the memory increase is much slower, and eventually stops before freeze

I shall add that I've already tried to switch those "sensitive" options on and off, like the one to reconstruct directshow after changing channel (that takes a lot of time), but to no avail.

Also, my CPU is constantly to 1-3% so no CPU speed problem.

@xmanlolo: did you try that "reset queue" trick?

I've just upgraded to DD 1.4 and now I experience some problems on some channels. I have choppy video playback on channels from the "Mediaset" network (italy), and also on RTL 102.5. Other channels play at a reduced frame rate, and the audio frequently pauses and skips. Recordings from these channel...
