newCS/Acamd gives "TVNZ" message when switching channel

[nordemoniac]

Hi!

I'm using NPVR, newCS and Acamd.

Acamd gives me this information when changing the channel. What does this mean?

Code:

15:58:42.137:
15:58:42.137: Ch: 261 - TVNZ
15:58:42.137: Programm crc: 177F7B54
15:58:42.138: PMT: ACamd_PMT.txt, search, not found PMT=0105 (AND SID=05E4)
15:58:42.138: PMT: chcache.ini, 0105,05E4,0B00,00000000,0064,0000,TVNZ
15:58:42.138: 0x0105 0x05E4 0x0B00 0x00000000 0x0064 0x0000 11111110

After this code, it takes 0,5 second, and the new channel is viewed, and decoding continues.
If I'm recording one channel in the mux, and I switch channels, I get the same message, and the recording gets a small cut (lasting 0,5 second).

Anything I should edit in a config file?

What capturecard are you using? I'v seen this occationally with my Technotrend 1501 card, I think it's a moment of confusion by npvr because the card hasen't actually started sending data from the new channel and the data it is sending is not valid. Nothing to worry about anyway as long as things work.

You can ignore the "TVNZ" in this acamd log message. Its just an unused field in the multidec API which is hardcoded with the value TVNZ because the application doesnt know the real channel provider name. This field is not used though, so is a non-issue. The rest of the fields in that API are set to real values for your channel.

It's my Terratec Cinergy C PCI HD card (yeah, I'm back again).

But my channel changes are SLOW!

The channel changes about 5 seconds after the last line in this log.

It's not related?

Hm, still having problems here.

Whenever I switch channels, it locks up for 2-5 seconds (depends on which channels I'm switching through). And if I'm doing a record on the same mux, I can see that my recording actually locks up too. So only is it slow to change channels, but it actually stops recording while waiting.

Anyone know where the problem might be? It's almost like the TV-tuner times out while changing channels...

I can't think of anything but a failure in the card itself, my Cinergy C PCI HD card has never experienced anything like that.

I have the same problem, using a KNC BDA DVB-C #1, driver version 2.1.1130.0, acamd0620.

As I said above - You can ignore the "TVNZ" in this acamd log message. Its just an unused field in the multidec API which is hardcoded with the value TVNZ because the application doesnt know the real channel provider name. This field is not used though, so is a non-issue. The rest of the fields in that API are set to real values for your channel.

Acamd uses the channel name and other paramaters (hash) to build a cache file where it stores the last used caid chid pmt and so on. You also can put this info in the ACamd_PMT.txt, infact you can copy the content of chcache.ini to the ACamd_PMT.txt file by stripping the part till the = sign on every line.
This solves also the pmt not found warinings in the acamd log. This doesn't work if the channel names are not passed to acamd in the right way.

I can live with the above problem, but the zap speed is terrible slow.

On other hardware it does work normal ? I can also test on my other pc which has Technotrend 1501...

Its not clear to me how Acamd is using these fields from looking at the Acamd files. You could try the attached patch though. It'll supply the real channel name if it knows it. There is times this code will not know the channel name though, and it'll supply the default 'TVNZ'.
