Incorrect Frequency and PID data from Autotune (1 Viewer)

[oil]

If freqencyes in file dvbt.xml are modified by devolopers, I hope that also this get fixed at same time.

Not only Freq and PID are wrong...

Not only Freq and PID are wrong, the language and other are wrong to...
This is a problem for SS2 because it's not BDA, and the little application ScanChannelsBDA.exe don't work- Than can't manualy put the wright parameters.

I have just tried CVS 07-27-2005--01-30 and it looks like part of this problem has been resolved, as Autotune now captures the correct Video PID for ABC 2 (2309).

However, many of the channel frequencies are still incorrect by 125 KHz. Of the 5 FTA networks that I have access to, Autotune gets the incorrect frequency for 3 of them - in fact, Autotune now reports all channels as being xxx,625 KHz, whereas 3 of them should be xxx,500 KHz. For example:-

Channel Seven should be 177,500 - but Autotune collects 177,625.
Channel Ten should be 218,500 - but Autotune collects 219,625.
Channel ABC should be 226,500 - but Autotune collects 226,625.

Channel Nine is OK at 191,625 and channel SBS is OK at 536,625

I have just installed CVS 07-28-2005--00-20 and as a work-around for the incorrect frequencies, I have edited the "dvbt.xml" file so that it contains only the 5 correct frequencies for Melbourne, and with the offset value equal to zero. So it looks like this:-

	<country name="Australia - All Regions" offset="0">
		<carrier frequency="177500" bandwidth="7" />
		<carrier frequency="191625" bandwidth="7" />
		<carrier frequency="219500" bandwidth="7" />
		<carrier frequency="226500" bandwidth="7" />
		<carrier frequency="536625" bandwidth="7" />
	</country>

Autotune now gathers all the correct frequencies, and all the correct PIDs.

However, I still cannot get the video to display for ABC 2 - it doesn't matter what value I set the Video PID to (in MP Configuration), the MediaPortal.log shows that it is searching for video at AE hex (174 dec). Here's the section of the MediaPortal.log:-

The green line indicates that the Video PID is 905 hex (which is correct), but the red line indicates that it is searching for video at AE hex. And the blue section is the indefinite loop that MP gets stuck in - which I can interrupt by selecting another channel.

The value of 905 hex is 2309 dec, which is correct for ABC 2. But, I can change the value in MP Configuration to anything I like, and MP will still only use the value of AE hex.

Can someone tell me where MP gets the value of AE from? Because it is clearly not taking it from the data in the TVDatabaseV21.db3 file.

I have also noticed (which may be related to the above issue) that I can set the AC3 PIDs to 0, and MP will still use the original non-zero value - again, where does it get that value from.. :?

Apart from ABC 2, all the other channel changes are now really quick and very smooth - there is no longer a pause and a break in the sound a few seconds after changing to a new channel. So, if I could solve the ABC 2 issue, it would be perfect...

please email the PMT file for this channel to e.beckers@gmail.com

I have installed CVS 07-30-2005--01-14 and I can now receive channel ABC 2 without the video freezing....

In fact, I can now switch between all channels without any "frozen video" or blank screens. The Video PID for ABC 2 is now correct in both the channel data and the pmt data...

However, Autotune still selects the wrong centre frequency for 3 of my 5 channels (I workaround this issue by using the modified dvbt.xml file listed previously) and deleting the AC3 PIDs from the channel data does not seem to remove it from the pmt data - for example (this is for channel Nine, where I have set the AC3 PID to 0):-

I am not sure if this is having any negative impact, although the audio does "stutter" a few times for the first few {5 to 8} seconds after a channel change.

Just tries cvs-07-31-2005--08-28.
No luck - it now says that my TV Tuner does not support autotune......

same problem here. nothing worked after the CVS installation so i re-installed the 0.1.3 version and it worked - but still with wrong frequencies (and autotune it did not find all tv channels (pro7 sat1 orf at astra 19,2°)btw)

@ wiggums and @ tijera, the "start.bat" file that was provided with recent CVS releases was incorrect - it did not contain these 2 lines:-

regsvr32.exe /s "%~dp0MPTS.ax" 
regsvr32.exe /s "%~dp0MPSA.ax"

However, that problem has been corrected, so you might want to try the latest CVS with the corrected "start.bat" file?

Taipan,

Off-topic, but just want to say thanks for doing a lot this CVS testing with the DVB tuning and stuff. Unfortunately, I don't have a lot of time at the moment to do this, so without your efforts, some of these issues would not get ironed out so quickly.

Thanks mate!,
