I'm sorry to hear you wasted your money on TDT+.
PyTivo is a vastly superior solution, and pyTivo + vidmgr just blows the doors off TDT.
If you really need streaming, StreamBaby does it, but I find the 1G file limit to be unacceptable. I don't find the fact the video is copied to the hard drive with pyTivo to be a significant limitation.
What's more, since both are written in Python, they should run on just about any platform you can imagine, including Linux, OS/X, or even OS/2, AIX, Solaris, or VMS.
I have over 12T of video files - more than 1800 files, and vidmgr works great:
