MyTheatre is a SOB the first time.
I've had it running on both USB receivers and PCI cards.
It may be the best, but a lot of the setup is magic, and I'm not vouching for its stability.
DVBdream, once I got a PCI card and was able to try it, and ONCE you get past the whole different interface, is actually easier to set up.
HOWEVER, I just ordered an FTA stand alone box due to frustration over several years with all of the above.
I suspect that won't be so hard, because of all the neglect and abuse I've suffered with the computer based solutions.
Yes, both programs have signal strength and quality, and DVBdream has CPU usage, if I recall.
...right out there under your nose, not hidden in a menu...
While I've been happy with Standard Def, I must say I'm not fully operational in HD !
Tonight, I'll be reviewing interrupts, and cpu-loading, and other fun things.
I've already doubled my signal strength by increasing dish size and going to a better LNB.
