OK, so I have to wait until fall to see 125W. Love the music choice channels. Well it's here and motored over ther. I am using a TBS5927 that is supposed to do ACM. Tried DVBDream and DVBViewer. I could not scan in anything on that TP. Pulled the TBS5520SE of of Linux and put it on the windows machine. Scanned all the MC channels in fine and they play fine in DVBViewer but not in DVBDream. Dream tries, but can't pull it off. I know I am a little weak with a 14.8 SNR on a ACM signal, but is the 5520 tuner that much better?

Interesting post. It grabs my attention because TBS has been on my mind for a long time.
What gets me is your findings, Comp. The card specifications state their capabilities. So they should do what they are advertised to do. But it looks like you have some variables going on. Card choice and software to run them.
You say the 5927 is supposed to do ACM...errr VCM? But it wont. Strange. Because I don't have a card yet. I wonder why it wont. What if you manually put in the tp settings?

The 5520SE does fine? Is the 5927 supported in Linux? And if so how does it compare vs Windows in functionality?
I've read a little on Crazy Scan. Is it a brute force scanning tool?

Because I'm not real versed on blind scanning and can only compare it to how my ham receivers work with their scanning functions. Do your cards simply miss scans because they (software scans) run so fast, or is it something else?
I can set my Icom to scan a frequency range and log those received frequencies. It will scan over and over until I hit stop. And in the course of time, log periodic transmissions.
For the guys who find wild feeds. To me it seems as if they bang a transponder scan over and over looking for a channel to become active. But again. I dont know. I need some insight I guess.

I wish these applications would let me link my satellite receivers to them over TCP/IP. Or even if there was a Linux-esque version of a BDA driver that would let me.

My friend had a chinabox receiver that would get Velocity/Motor Trend. It was a FTA channel. Yet when I entered the tp info in my Os Mio and zereoed in the sat. Nothing. I still dont know how he did it or why mine didn't see it at all.
That was months ago. I gave up trying.

Actually Arlo, both tuners will blind scan and lock the Music choice TP, but only the cheaper 5520Se will scan any channels in, and only in DVBViewer. Been busy today, so will try in Linux tonight and see what happens. PS, the 5520 is a real slow blind scanner, were the 5927 excels at it.

Confirmed through multiple tests with both linux and windows the 5927 will not receive the music choice channels, yet the 5520SE does just fine on them. Verified by Major Tom on Rick's before I got booted again for saying something he sells won't work with them. Yet Majortom is still there.

Rick must be hurting bad, or getting senile. I know he will read this post as he sent me a email months ago when I said this. Since them he had added a donation page and has been ban happy when anyone mentions a problem with anything he sells. A active conversation that his gods agreed to and Me under a fake alias gets banned for saying the same thing. You guy's are cool and don't have to worry about stepping on eggshells while posting the truth. Special shout out to Michael! I need that forum like a nother brain tumor removal. Been at this along time and know what I am doing, rather help were it is appreciated.

TBS6903 works ok with the 125W radio channels, at least on my system. This is the older version though not the new incarnation of the 6903+. I use SmartDVB most of the time, EBSPro for scanning. Have several other DVB related software but those two are my go-tos.
I have a 5520SE and was not able to get the 125W channels with it for some reason. It only worked for a couple months and died. Bad investment...

Weird, mine is just the opposite. EBS pro scans them fine with the 5927, but they will not player in viewer, or dream. Swap to the 5520SE and they work fine. I have tried every driver made for the 5927 and same result. Have also found a couple of other ACM signals that are the same. Sometimes I wonder if it is my AMD based system causing the problems. Although Major Tom can only get them on the 5520SE and not on the 6903, witch is the same tuner and demod chipset. He is strickly Linux, and I use both, so thinking shady drivers.

The 5520SE never worked well for me in either linux or windoze. I had it working momentarily with a raspberry pi, was able to play one channel for a bit then it stopped receiving. Worked with windows 7 but not very well. It was powered though the USB port and I am thinking it might have been power issues because the unit would get very hot.
The 5520SE is supposed to do S2x where the 6903 does S2 and not S2x, so I would have thought they are a different chipset. Then my 6903 is 2-3 years old and apperently the newer version does do S2x, so the chipset likely changed. Not sure why they use the same model number for different hardware... makes it confusing. Looking through forums there seems to be driver issues with the new 6903 configuration. Maybe TBS will update the driver or someone else will write one that works... Maybe Crazycat has something in his latest package?
