Just a FWIW on the 1000.2 option. In my setup, I found that the genpix could not supply enough power to make the switch work properly. I found this out when I disconnected a dreambox that was connected to a second run to the dish. I'm pretty sure you will need another receiver or a power inserter at...

The only AC3 decoder that I've had any luck with is intervideo.
I haven't spent much time trying to figure out why but it works well for me.
Worth a try.

In my case it was trial and error. I started with the info in the other thread and had to fiddle with the commands until it worked.
The first three should be fixed and the last set (F0 to FF) should select the port.
F6 didn't work for me but FA did.

This is just a guess, but I'm thinking you might need to use the raw diseqc commands to control the switch. It's worth trying. Just select "none" for diseqc in the options menu and then add the sats you want. In the sat menu use the raw commands that are in the thread that I pointed to. You may have...

Works fine for me. Try uninstalling and then re-install and see if that fixes the problem.

The patch is included in the latest download.

This just started for me too.

For number 1 you might want to try installing the intervideo audio codec.
AC3 audio worked great after I made that change.

I just checked HIST-HD on 129 with about 60% signal level and I'm not seeing any stuttering or dropped frame but the cpu usage is about 50-90 %. I have been switching back and forth between Vista and XP and I'm pretty sure XP has lower cpu demand but I'm still testing. As per rel' post on codecs, I ...

I don't have an ati card to compare but the setup I'm using with an 8800GT seems to work pretty well. Fairly high cpu usage on a dual core 1.86 Ghz system running Vista home premium. Typically 75-90%. Video Codec.....: ArcSoft (v2.21.31.21 - 14/12/2007) Audio Codec.....: InterVideo (v4.0.11.83 - 24/...

Same thing here but seems to run ok if I run as admin.
1.4h didn't have this problem.
