View Full Version : DVBViewer and Bisat

I have a Philips dual sat dish and a twin LNB. Things work just fine on our two receivers, but on my SkyStar2 (the signal goes through a receiver which is obviously never on when I make my tests.. otherwise I couldn't switch between sats).

I set up DVBViewer to use the proper DISeq for each sat, and did a channel search, which came up with quite a few more channels than the default channel file that ships with DVBViewer (TE edition btw). However, for about every 2nd Channel on Hotbird (DIseq B), I get a cannot locate B2C2 MPEG-2 Filter Audio/Video Ctrl. Interface error 91000101. So far I've found DVBViewer the best app for my card but before I invest the 15 Euros for the full version I'd like to have this settled.

maybe bug in the used DS filter, afaik their are two, SkyAVC and internal, maybe dvbcore based apps work better, for instance DVB Explorer, Mytheatre 2.76 or KeyDVB or you could try to import a SatcoDX list. I don't receive a single channel on hotbird, I'm to lazy atm to check my dish. One thing I have learned being a long time SkyStar 1 user is there is always something not working or missing therefore I wrote my own app the first day I bought my SkyStar 2

well i would not recommend using the dvbcore engine at least for the skystar2. The problem is easy, Saar hacked the driver to get it work and to be honest a couple of things he changed are not that nice. In my case i was unable to control my DiSEqC v1.0 Dish and in other cases the "updated" driver was rewriting the eeprom, which produced damages on the card.
The error about "cannnot locate Audio/Video Interface" is quite simple.
1. it appears if you try to tune in non free to air broadcasters
2. it appears it the a/v pid are set wrong (if the scanner was setting the channel, then at least this fact can be excluded)
3. it appears if the receiption signal is too weak (but in this case normally a message concerning the tuner status appears)

maybe I'm having this diseqc problem as well, I'm wondering if there are any good channels on hotbird? The other problem is I don't know how to switch between 4:3/16:9 but since I'm recording only I don't care

Hmm, Hotbird 13° is probably the most multicultural satellite system in europe.
There are a couple of interesting channels. But in my case i only watch a few of them. Giga for example is quite good for relaxing ;)

Switching between 4:3 and 16:9 is - if you use the DVBViewer optionally done automaticly. The only problem which is existing, is that sometimes it happens that you when you start recording a movie it's 16:9 and in between it switchs to 4:3 (commercials). The most authoring tools are getting confused, since they are just reading the resolution out of the first PES-package... The dvbviewer itself checks each package if its resolution fits into the actual one. If not it simply manipulates the aspect ratio. If also the video resolution changes it rebuilds the graph. Same on ugly mono<->stereo channel swappings. In comparison to plain audio- video playback, the tv broadcasters are "ugly" flexible...

I'm using my own GPL'ed private C# app based on dvbcore/coreox, since I record only via scheduler programmed by TV Movie ClickFinder and this is working the development has stopped some time ago. The only thing left to do is to setup my recording machine and to integrate the nvram wakeup tools

1) Doesn't DVBViewer mark encrypted channels differently? Either way, we're definitely talking about free-to-air channels like ARD, ZDF, etc.
2) As you said we can exclude that.
3) I've never gotten such a message. What should it say? There's a different error I sometimes get (Cannot set tunerstatus (wrong settings), error 90010115) but that's nothing about a weak signal, is it?

The funny thing, our rather cheap Pixx receivers have no problem switching between channels, and I got the Diseq settings from those receivers (interestingly enough.. initially no Diseq was configured and it still worked.. just not so well and I was getting either of the mentioned messages quite often.. but not more often than now where I have downloaded the most recent transponder files and done a channel search).

The DVBViewer marks the encrypted channels. Each non fta channel has a so called ECM stream which is used for transaction with the descrambler device. If the scanner detects such a Pid in the PMT Table of a channel (this table contains all necessary pids for each channel) it marks the channel as decrypted.
One reason for problems with tuning channels is also a possible dejusted dish? Even if the signal is powerful it might be that the data error rate is too high - caused by a squinting lnb? You can easily check this by clicking onto the setup4pc tool and opening the status window. Normally the error rate is 0, the higher the worser.
The tunerstatus error message appears if the tuner on the card is tuning a transponder, but no signal returns.
The (dis)advantage of cheap dvb receivers is that they have an mpeg2 hardware decoder on board. These decoders does not take care about resolution of the mpeg (at least if its not HDTV) and if the stream starts with an I-Frame etc. This is why they are so fast, but if you use DirectShow (tm) you have to read the proper video and audio resolution first before you connect your sourcefilter with a decoder.

Take a look at ProgDVB (www.progdvb.com). I find it better than DVBViewer.

Sorry, I just read the thread about multilanguage capturing, and I found you alreay tryed ProgDVD. :rolleyes:
