Changing channels takes 4 seconds?

[peek]

Hi,

 

 

I was planning to use DVBViewer as a replacement for my dreambox but, as the subject says, changing (encrypted) channels takes about 4 seconds compared to my dreambox's 1,5 second. This is clearly a big step back in performance... Changing a non encrypted channel is a lot better at 2 seconds per channel switch.

 

Is there a setup (hardware/software) possible where the speed of the dreambox can be matched? Or is viewing DVB-S on a PC always "slow" compared to a dedicated dvb box?

 

I'm using a Terratec cinergy S2 card with CI & CAM and the latest drivers connected to the same LNB's as my Dreambox (see the support file for further details).

 

thanks!

PS I'm NOT blaming DVBViewer for the slow perfomance as it's not clear what is causing it.

Try Options > Hardware > New tuning method

If you use no DiSEqC go in the Channel editor and select the main group and set DiSEqC to none.

 

All other tweaks are already set.

 

If that do not help may be the driver or the CAM are the slow part.

I have no own experience with encrypted channels. But read from channels charges in less then 3 seconds by encrypted channels.

The terratec itself switches in normal time over here. The problem is the encryption which needs some time. Especially if the mux is switched. A different CAM can help a bit, but don't expect too much.

Tjod, changing to the new tuning method slightly improves the performance but it still takes about 4 seconds to switch.

 

I've tried the CAM in my dreambox and it can change channels in about 2 seconds (slightly slower than my [removed]).

 

So I guess that the Terratec hard/software isn't very fast? Are there other DVB cards which are known to be faster?

 

thanks!

channel switching on encrypted channels takes on my floppyDTV-DVB-S2 2 seconds.

FTA is faster, just under 1 second.

 

Channel buildup on nvidia cards is a biet slower then ati cause of the weird way an nvidia works with protected channels= read,

no unencrypted data may pass the pci express bus and nvidia card must pass the cam twice.

That sounds a lot better than the Terratec which I just bought!

 

At least my videocard is an ATI...
