Hi,
Thanks for your information.
Could you tell me that the "HD" channel is DVBS2 signal？
Is the normal and fast channel DVBS signal?
We have some reason on why locking DVBS2 signal be slow. The demodulator chip will scan the DVBS signal at first,then start to scan DVBS2 signal.So it look like DVBS2 signal will take more time for tune.
I could try to improve the locking time,but if i reduce the lock time for DVBS,it will cause some weak signal can't be lock.
It's really hard decision,we sold this product to world wide,not all people have strong signal just like European.
I can give you some test driver next week.
Thanks!
The above explains why ITV HD tunes fast as I believe it is still DVBS - BBC, CH4 are DVBS2 thus the slow changes, surely the data is in the transponder to just tell it to go straight in with DVBS2????
And why can't it tune faster for people with 85-90% signal
Anyhow - lets see how the test driver works when he sends it over to me.
DJBlu - I have attached 2.0.0.18 drivers if you want it, this tunes quicker for me as it stands atm (around 2 seconds faster)

onetoomany did you have any luck merging the custom data grabber with the V2.0 mod?
This is rubbish news.
Cheers for the driver.
Surely they can tell the chip to scan DVB-S2 first and visa versa should the driver request it.
Bit poor if you ask me.
No - to do the merge I'm having to wait for DJblu to move his code into git. That way git does all the merging for me, especially given that they are both changing the same dlls (unless anyone knows of another way...)
Ah ok onetoomany - thanks for taking a look tho!

many thanks for fixing the Diseqc part in MP!!
I just wanted to report that your fix is working fine with my TBS-6964 Quad Tuner Card and my Technsat Gigasystem 17/8 Switch ..all 4 satellite positions can be tuned without issues so far.
...keep up the good work!
best regards,

Hi
I'm in receipt of the test driver - I sent to DJBlu to test as-well.
It seems to make the DVBS2 tune faster, whilst the DVBS tunes have increased their lock time.
With the new test driver I experienced a complete tune failure, mediaportal had a spinning logo for around a minute before it recovered into the guide and I could tune again. Didn't take note of the time so I'll re-test later and log the time of this.
Looking at logs - tune times appear to be quite fast - matching or beating the 2.0.0.18 driver times.
However when testing and switching driver, the 2.0.0.18 driver appeared to be faster when zapping - I'll double check this later with a stop watch .
Not sure if you have had time to confirm my results DJBlu?
Thanks
Ian

Looks like all they have done is flipped the priority of the DVB-S and DVB-S2
The timings are the same for DVB-S2 as they were for DVB-S
Bit shite if you ask me.
I'll get intouch and ask if they are able to let the driver be told which to use.
