I am trying to debug why I am getting the "UnDRM.log never seemed to appear in /dtv" error and found something that has not been mentioned in this thread (at least I did not see it). I am new here and not very familiar with Samsung TVs and ARM architecture but I am a software developer so I am familiar with the debugging process. If I can get some help related to Samsung-specific details, I might provide some help in figuring out the issue.
The TV is EH5300 with firmware 1023.2 (it was running a near-original firmware but the latest skype-like root did not work, hence the upgrade). For the moment, I am working with the 1.7.3.31 version of the software since I could not get the latest version working properly.
Here's what I get when I start the program:
Here's the output when I try to decode a recording:
Here's the output from the netcat monitor at this time:
Note: sda1 is the device with the recordings. sdb1 is a USB stick with media copied from PC.
It looks like samyGOso does not do anything and return. I tried to find out what it does and it looks like it injects some code into the TV process. The "-A" switch indicates the target is exeAPP process. However, on my TV, no such process exists. Here's the output from the putty terminal:
Since exeDSP exists, I changed the command-line to
Here's the putty output:

I have read many of the pages in this thread, especially the ones about the specific error I am getting. Maybe this is the reason some of the users are getting this error. However, I do not know what the actual decode command is so I cannot try it in putty and see if it works. I also thought about changing the command-line that gets sent to the TV, but since I do not have the source code for the app, that is not possible.
Any help getting towards a solution is appreciated.
Note: Another data point is that even though the program is running telnet on port 1023, I execute putty on port 2023. Telnetting to port 1023 gives me a prompt that does not seem to do anything. Any command I type results in "not found" error. However, PVRDecoder only works with this port.
I do not know the significance of this but I wanted to mention it in case it helps someone understand what is going on.

It looks like samyGOso does not do anything and return. I tried to find out what it does and it looks like it injects some code into the TV process. The "-A" switch indicates the target is exeAPP process. However, on my TV, no such process exists. Here's the output from the putty terminal:
