So far it allows you to use two codecs (nuppelvideo and mpeg4) but for some reason I get a bit better performance with the nuppelvideo stuff so I stuck with that.

Re:I wish I could find some .... USE MythTV!! (Score:2)
The biggest problem is that the architecture is based around software codecs which requires reasonably hefty CPUs. Hefty CPUs (eg, Athlon 1800) need hefty fans and big boxes. Hefty fans make a lot of noise, and big boxes are, to my eye, far too large for audio/video equipment, and often (but not always) plain ugly.
Isaac has made it clear that he intends at some point to support hardware codecs, but the timeline for that is unclear, as it requires support in a number of other areas (eg, xvideo).
My assessment of the current state of MythTV is that it looks great, has a nice interface, does most of the things you would want a PVR to do (and the list of unsupported options is getting shorter and shorter by the day), but as no hard-and-fast guidelines about supported hardware have been established, getting it to work on your particular box can be a hassle (but, might not be, if you get lucky with choosing the right hardware; unfortunately, there isn't a good published list of the right hardware). Unfortunately, MythTV requires a large handful of other packages, and getting exactly the right versions of each can be frustrating at times. While the project has considerable promise, and I have every expectation that it will eventually be excellent, it isn't quite ready for prime time.

This isn't a replacement for the Dish subscription. Dish is sorta-kinda DVB-compatible - you can use a DVB receiver to pull in some of the Dish Network channels, but only the channels that are unencrypted. Which means that you won't get the channels you're probably most interested in - this box will not get you free HBO or free PPV movies, for example.
And just to round out the picture, DirecTV's feeds are entirely incompatible with DVB, so you won't pull in any DTV channels.

Obviously you're one who thinks that the performance of PowerPC expands to beat any competitor at any given time. While the x86 and PPC are not comparable MHz for MHz, you can certainly figure out how much work each one does per cycle. Just for comparison, a dirt cheap throw away CPU nowadays would be a 1GHz Duron (around $35), which runs four times faster than this particular PPC. The PPC would have to execute four times more instructions per cycle than the Duron to be roughly comparable, and you can bet your life that it doesn't. So, all in all, while the PPC might be more efficient per cycle, it is not per dollar. IOW, for any given dollar amount you can buy considerably more raw processing power in an x86.
For example, check out the Epia boards from Via. For around $100 you get roughly the same processing power plus all conceivable peripherals on board. Add a $30 graphical LCD from Crystalfontz, get (or make) a suitable case, and you're set for WAY less than $500. Especially if hacking is what you want anyway, this approach is much cheaper and more flexible (not to mention more fun).

Not really, unless you're talking battery operated, or are dealing with extreme heat generation. Judging by many embedded systems nowadays (e.g. set-top boxes from cable providers), heat generation IS an issue, but you didn't specifically address that.
Besides, I was being very generous comparing the 250 MHz PPC to the 1 GHz Duron, because they're certainly not in the same performance class. Don't forget that the Duron itself has a work-per-cycle advantage over Intel, so it's no slouch either. Plus, while I don't know too much about the PPC, it's still an old school RISC design if I'm not wrong, meaning that it has fewer complex instructions and might require more of them than an x86 to accomplish some things (fp math/fancy addressing).

That's right, and that's why it might not make much sense for most of the applications people are salivating over here. The cheap (but potentially hotter, though still fanless) Via Epia boards are perfect for these geek-type "embedded" applications, such as MP3 and MP4/DivX players (though the jury is still out on whether the C3 processor has quite enough juice for the latter). The extra heat and power won't matter much, but the very substantial cost savings will.

You are right. I had an application running in a 350 MHz AIX box, migrated it to a 800 MHz Pentium and now it runs 5+ times faster. Conclusion: with the same clock speed, a Pentium is 2.2 times faster than a PowerPC. Therefore, that 250 MHz PPC is equivalent to a 120 MHz Pentium.

Magically your receiver is now married to a different smartcard.

One quick example, Know how they tell you that they can't remove a pay per view event from your system if you pre-order it? That's not true. Most agents simply do not know how to remove them, hell most supervisors don't know how. But it is possible.
Echostar intentionally keeps information from the public, and even their employees to maintain a level of security through obscurity.

I'd only add one small thing to this. You're absolutely right about not being able to pick up DTV channels - DirecTV has their own proprietary scheme which is incompatible with DVB. But Dish, OTOH, does broadcast some channels unencrypted, which you can pick up with a DVB receiver - the Lyngsat site can tell you which ones are FTA.
