Getting started with DVB-S on MythTV

**receptiveit** · 09-10-09, 08:17 AM

Hi everyone,

I currently have a working MythTV setup with 2xdual DVB-T tuners (Hauppauge HVR-2200) and a single PVR-150 that is connected to my Austar set-top box via the Composite input. This has been, and continues to be acceptable, but I wanted a tighter integration.

I have read that some users here have had success with the Digiwave 103G, so I purchased two of these units. I installed one of them into my production MythTV backend (MythBuntu 9.04 64Bit) and was pleasantly surprised that it was detected on boot.

Unfortunately, that is as far as I have travelled. I have extracted the relevant information from the set-top box (frequency, polarisation, lnb frequency, fec) but I am unable to tune any channels.

I understand that most of the channels on Optus C1 are encrypted, and I haven't started with the soft-cam yet, but I was under the impression that there is one channel on the Austar frequency that is unencrypted, and even if a channel is encrypted, the transport would lock.

It is probably something I am doing wrong as I have never played with DVB-S in a Linux environment before.

Any insight would be appreciated.

Just out of curiosity... What are the specs of you backend PC?? I assume fairly impressive for 4 x DVB-T and 2 DVB-S??

Backend machine is a Intel core2quad Q9550 (2.83Ghzx4), 4GB or DDR2 RAM and a Intel 16 port RAID card with 6 1.5TB disks in a RAID6 array.

DVB-T is only intensive on the disk, as the backend does not have to encode anything. It just pulls MPEG-2 off the wire and saves it to disk. Disk IO does take some hammering when I am recording multiple HD channels and watching simultaneously, thats what the hardware RAID is for.

My current Austar configuration gets brought in via a PVR-150, which has an on-board MPEG encoder, so the CPU still does not have to do any work, just save the MPEG stream to disk.

My backend is fairly grunty, but is over-speced for the job. That's my usual motto.

Just an update.

So far, I have tried scanning using the initial scanning data for Optus C1 in /usr/share/dvb/dvb-s/OptusC1-156E - No transports found

I added the details I pulled out of my Austar set-top box - Frequency:12478 Symbol Rate:27800 Polarisation:Horizontal fec:3/4

After adding the above details, I tried scanning again - No transports found

I tried setting the LNB type - My set-top box says the LNB frequency is 10700 - The only setting that allows me to scan is "Universal", but I think that is wrong.

I've currently getting no-where fast, so if someone has some sort of insight, it would be a big help.

And just a quick note for anyone wanting to set up a HVR-2200 (Dual PCIe DVB-T) under Linux. In Australia, the DVB-T transmission frequency can be offset by +125Khz or -125Khz. I have the issue that I needed to manually scan using the latest version of w_scan and manually set the transports in MythTV.

Now my cards are working beautifully, but it did take a few weeks of work and much discussion with the v4l driver developers. Steven Toth and Michael Krufky are really nice guys.

Hope this helps someone out there.

Another update, I have had some limited success.

I seemed to have overlooked that using the -l option with the scan program, you can set an arbitrary value. So I just set -l 10700 and I was able to see some transports. Unfortunately, I could not see any transports on 12478000:H:27800000:3/4

Is this the proper Austar frequency and details?

Another update. I have modified my initial scanning data with the information from Lyngsat. For completeness, here is every transponder I found on OptusC1. I can now lock on to channels, and I can move on to the soft-cam.

Where's Aljazeera 12365 V 27800 1121 1122 1121

Gee's..... ya cards not that good after all!

I am not proclaiming to be an expert on DVB-S. I am just trying to replace my Austar set top box with a PCI card in my MythTV box. This is my first attempt at getting it to work, and I rekon for not getting any help I am doing okay.

What kind of setup do you have?

Do you have some pointers for me?

Saying my hardware is crap is not really helping anyone. I bought them because I read in another post that covert has these same cards and they are working well. Even my local computer supply shop ran into a brick wall when looking for DVB-S cards.

Well done getting this far. One step at a time.

Might have bad news for you... I don't think the Austar card is going to working on a card server. Check the other sub forums on here and see where Austra is at with card serving. You might need to get a Foxtel card to proceed.

BTW Aljazeera works just fine on the 103G's. Thats if you want to watch that..

I'm not 100% sure, but I was under the impression Austar would be easier to get working than Foxtel. Austar uses Irdeto2 for their encryption.

I have recently read that you need to pair a card to decoder, or something like that.

Unfortunately since I live in a rural area, I can only get Austar.

I'm a little confused and it is getting late.
