Since a while (not only with 1.2.0 my TV server has a strange behaviour. Yesterday I did a upgrade install from 1.2.0 RC to 1.2.0. I recognized that my DVB-T cards appers twice in the card configuration. I cleaned it out (remove card and related channels in Config and remove USB stick of DVB-T card). Then placed back the stick, card was deteced and seen in config. After the scan it was working ok.

Today now I get this picture (see attached file): DVB-T card appear 3 times (2 with unknown (id 7 and 8) and one as DVB-T (id 9). Of course now it is impossible to view the DVB-T channels (e.g. SF1). The device path of the id 9 corresponds with the one used in the windows device manager. The stick was not taken out.

What could be the reason?

Hi HACH

What could be the reason?

This problem can happen with USB tuners. What is happening is that the system device path for the tuner is changing. That means that Windows is changing the "address" for the tuner. When Windows changes the address then TV Server thinks it must be a new tuner. You may not be able to do anything about this. I would recommend always using the same USB port for the tuner, and don't unplug and replug. Using standby + resume might also cause this problem.

Do you have other USB devices?

Thanks for the hint mm!

I have only one USB TV-Card. Without unpluging/pluging the USB stick I can reproduce the event when I shut-down the Server and start it again. With standby I cannot reproduce it.

Are there means to prevent windows XP to re-scan USB ports?

I have only one USB TV-Card.

But do you have other USB devices (not necessarily TV tuners).

Without unpluging/pluging the USB stick I can reproduce the event when I shut-down the Server and start it again. With standby I cannot reproduce it.

Not that I know of. One thing you could try: increase the "delay before TV Server detects cards" setting in the "general" section of TV Server configuration. Wiki details are -->here<--.

Following devices are connected to USB of TV server:
- PCTV card
- mouse
- keyboard

I'll try out the delay tonight.
Thanks

Hi again HACH

Did the delay help?

Hi mm

was in holidays for a while.
Put the delay to 5 seconds. Looks ok so far now (i.e. no replication anymore).
Thanks for the hint.

I was to early to take off the warning: same error pops-up again.

I'm sorry but I don't think there is anything we can do about this. You would probably have the same problem with other software...

The best that you can do is map the channels to the "active" tuner and delete the "inactive" tuners. That should take about 20 seconds. No need to delete channels and rescan.

Not sure if it will help, but you can use the MS 'DevCon' command line device manager utility (see link below) to add/remove/restart devices - if you ran this from a batch file etc on startup it might be possible to 'clean up' the spurious USB tuners before TVserver looks for them.
