Channel changing unreliable, 110 119 and 61.6

[friken]

My Setup:

Skywalker-1
Windows XP
DVB Dream 1.4i
em**ation 3.0.4.9

2 physical dishes, one has a twin LNB (unknown type... not sure twin dishpro or legacy twin, but both 119 and 110 output is on one cable from the dish). Dish 2 has a single LNB and pointed at 61.5, single cable.

I have both cables (one with 110 and 119 and other with only 61.5) going into a DP34 and one output cable from dp34 to the skywalker-1. Note: I also have a diseqc switch which I have tried instead of the dp34. Either way has the same problem described below:

With this setup I do get channels both sd and hd, they look/sound normal. The scanning worked normally and I have all the chans I would expect per sat. The problem is changing channels is unreliable. If I change channels on the same sat (ie all 110 channels) everything is good. When I change channels to a different sat, I have a 50% chance of the channel change to fail. Signal will show 0 sometimes and sometimes show full but not actually tune. When this happens I have to change back and forth a few times and eventually it will tune correctly. It doesn't seem to be only one sat the error happens when going from 61.5 to another, 110 to another or 119 to another.

I've been reading the forums like a mad man and have two ideas not easy to try:

1. add old receiver to the setup to power the switch. The skywalker-1 outputs 750mA which they claim is plenty, so this is a long shot idea. And I don't own an old receiver.

2. replace the twin LNB with something newer. The equip was on the house when i moved in and is old. If I try this, what LNB should I buy to replace it?

3. Run two cables from the twin LNB to the DP34 or diseqc in hopes that the 110/119 in single cable is the issue. But I doubt that will fix it because both cables will have both 110 and 119 with the lnb I have.


Ideas?

check your cable connections and replasce any corroded ones, make sure that you have it properly grounded, I have experienced the same thing and for me it was a grounding problem that fixed it.

What is the version number of the genpix unified driver you are using with dvbdream?

What are your computer specs?

What are you diseqc settings in dvbdream?

What codecs and renderer are you using?

I have this problem as well. I am running 2 x twinhan 1020a under two separate instances and my channel changes fail about 33% of the time. I only have 110 & 119 setup through Diseqc ports 3 & 4.
