I'm trying to add some DVB-S channels using a Twinhan 1025 PCI card. I'm able to get a signal lock when scanning for channels in the myth setup (backend setup), but it will not pull in any channels. I know everything (dish, motor, lnbs, switch, etc) are working because I can plug the same cable from the mythtv box into an STB and it works fine.

Actually, I was able to pull in some channels once. During the scan, the signal lock went to no lock and none of the scanned in channels would work. I can't figure out why that was, so I deleted the channels out of that source and tried again. Now I can get lock, but no channels to come in. I've tried various sats and tp's.

So, before I try to muddle my way through the dvb-utils and create a manual channels.conf file, did I miss something? Looks like I have the dvb tuning timeout set at the maximum level. Can I extend that somehow to see if that would help? We have LOCK, after all.

Next thing to try is a scan from an existing transport rather than a full scan. I just thought of this while typing. I've only been doing the full scan. Of course, I have to wait for the wife to quit watching Lifetime Movie Network first. Could be a while.

I added a new transport (freq 3824000 and symbolrate 3617000). When I went to scan for channels, I told it to scan an existing transport and selected the newly created transport. Still the same results. Locks, but then times out.

I stopped the backend, but could not get the card to tune using:


I'm not sure why the L band freq is 0 and the Srate is the way it is.

The switching, motor moving, and signal locking are all working in the backend setup, but why am I not getting any channels to show up? We're locked, I know they are there, everything appears to be working, ah, so frustrating.

Update: I pulled the 1025 out of the MythTV computer and placed it into a Windows machine. Strangely enough, the exact same thing happens. It locks, and then no channels are brought in. Looks like I'm going down the path of a bad card.

Why does DVB-S hate me when I love it so much?

OK, I've determined that the card works in Windows using ProgDVB.

Now, I've replaced the 1025 with a 1020A. Booted up, went into the backend setup. Got out of that and went to the command line and tried what I had tried above. Still the same issue:



About at my end here.

I have the same card and have alot of issues with channels locking. But, in order to get channels while scanning I had to patch the dvb_ng fixes from http://opensvn.csie.org I actually recompilied for sasc-ng and the patch is part of the process. I only had really scanning issues with D*shnet. Bev worked right out of the box. I have channels listed but I have a hard time gettting lock and on the signal meter usually comes up with 25% signal and 8% noise but, it works with those values if they are in the teens usually get signal fade and pixelation. I have tried using 2 different diseqc switches and a 22KHZ switch if I find any thing out that will be useful in this endevour I will pm you. Oh by the way what bird are you trying to get.

sorry the correct addy is svn co http://opensvn.csie.org/myth_dvb_ng

I'm not scanning any of the dish network or express vu sats. I just want true free to air.

Seems as though the channels I was trying to scan in on AMC3 C band just won't scan in. It says something about no tables...as if it can't find the channels.

However, I scanned in the Equity mux on G3C Cband and also the ION mux on AMC1 @ 103W, which pulled in all expected channels. BUT, when trying to watch them, signal stays at 0%. I haven't figured this out.

UPDATE

Poking around on the MythTV.org and linuxtv websites, specifically http://www.linuxtv.org/wiki/index.php/Twinhan_VP-1025, I found a little tidbit on the 1025 DVB-S card I'm using.




The first statement there seems to coincide with the command line output I received in the second post.


Compile and install modules....wow. Where's a good place to read up on how to do this? Or, would I be better off just getting a different card? [/code][/b]
