Time to load driver for PCTV nanoStick T2 290e

Postby patrikp » Fri Mar 09, 2012 11:52 am

Hi,

I have a PCTV nanoStick T2 290e tuner. It is a USB-stick that is capable of receiving DVB-T2 transmissions. I have used it together with DVBLink TVSource 3.2.2 for a long time now. All works well, expect that it takes more than 30 seconds to tune to a channel the first time after the system has been idle. This results in a timeout in Windows Media Center.

I have described this in an older post: http://www.dvblogic.com/phpBB3/viewtopic.php?f=43&t=14300

Now I am investigating a move to DVBLink 4.x, and I would like to share some results with the community.

First I tried DVBLink TVSource 4.1.0 and amazingly the "first tune time" was only a few seconds! Great!
Then I tried DVBLink TVSource 4.1.1, and the slow tuning was back...

I guess this behaviour is controlled by the bda.dev file. Based on its size it looks like a lot has happened in it between 3.2.2 and 4.1.0.

Could DVBLogic please investigate the changes that were performed to this file between 4.1.0 and 4.1.1? It would be great if the tune time for this tuner could be as good in future releases as they were in 4.1.0.

I have pretty much the same problem with TT 3650 CI. I upgraded both HTPC hardware to get a stronger processor to be able to do better streaming to mobile devices. But now this annoying delay after the system has been idle for a while. What happened between 4.1.0 and 4.1.1?

I have the same issue to. After the stability patch in 4.0 (http://dvblogic.com/phpBB3/viewtopic.php?f=56&t=14835&p=48979), the tuning was fast. But when I upgraded to 4.1.1, the tuning is much slower again.

I have also seen problems with switching between dvb-t reception and and dvb-t2 reception, se my posts here: http://dvblogic.com/phpBB3/viewtopic.php?f=56&t=17195

For my understanding - are you talking about T/C or S/S2 TT3650CI?

I?m talking about TT3650CI for DVB-C/T.

I have two of them installed in my server and I have them hooked up to a cable TV source. One is showing free channels and the other one is showing encrypted channels. After running this for a while on my new server it seems that they are "falling a sleep" when they haven't been used for a while. When the server has been in some other mode than TV for some time and you turn on live TV it will take about one minute to actually show live TV, and if I switch to a channel on the other tuner it will again take one minute to show live TV, after that it will switch channels with no delay even if I switch between the tuners, I also noticed if you are watching a channel on one of the tuners the other will again fall a sleep after some time and switching channel to that tuner will take long time again.
This will also cause problems with recordings as I think the media center recording service are cancelling recording when it won't get TV signal that quickly.

Can you please set server log level to info, reproduce the issue and attach zipped dvblink_server.log here?

Here is a logfile attached. All is fine with changing channels back and forth until 19:26:19 when there are a request to show a channel from being idle for about 30 minutes, live TV is displayed 19:28:08 almost 2 minutes after channel is requested from the remote. It seems that the delay is when loading the bda.dev driver. Same thing happens again at 19:34:40.

Yes, I have seen it already somewhere. It just loads a dll and that takes a lot of time. Do you see the comparable delay when you open configuration settings of TVSource?

Just got the 290e stick, it will nstall fine in media center, but
In DVBLink won't find half of the channels.

It gets really poor signal even for main channels, which are 100% strength and quality

I did a test with another TV-Card, Digital Devices Cine. I did a complete reinstall of DVBLink and did a new setup. But I still have the same issue as with TT 3650. Oberon, any news to fix this? Starts to drive me nuts...

We could not reproduce it, but will be looking into it again.

I tried with another software (MediaPortal) and there my TV cards works good all the time, meaning it must be something with either DVBLink or WMC.
