Can't vouch for accuracy: Tivo: Best Quality 544x480 5800.00 kbps None High Quality 480x480 3500.00 kbps SVCD Medium Quality 352x480 2600.00 kbps VCD Basic Quality 352x480 1470.00 kbps VCD Many people record at 640x480 which outshines even Tivo's "Best Quality". I personally use 480x480, 3300 kbps (scaled) and mpg4 quality setting of 2-12. I couldn't personally tell this apart from 640x480, but maybe my tv isn't good enough (though it looks great to me!). By the way, "scaled" means that if you set mythtv to record at 3300 kbps at 640x480, then back off to 480x480, the bit rate will be reduced proportionally. Upshot is that if you are recording at 480x480 you are not really doing 3300 kbps. Anywho, the end result is the picture looks awesome, much, much better than my friend's Tivo at "medium". You will not be disappointed. Oh, my files weigh in at 1.1 Gig per hour. Your question about recording and watching at the same time: I couldn't tell what exactly you meant. So I'll just tell you how it is. Mythtv can record one stream per tuner card. It can also play one stream at the same time (assuming you have backend and frontend on one machine. "Live" tv is really just recording a stream, and then playing the same stream right away. So while your tuner is recording a stream you can a) watch that stream (ie "live" tv), or b)watch a different, prerecorded stream. Finally, if you have two tuners you can record two streams at a time and watch one of them, or a different prerecorded stream. That make sense? My *guess* is that a 2ghz celeron could handle two tuners, but I'm not sure. Finally, easy factor: If you are careful to pick motherboards, nics, sound cards (or a motherboard with those built in) tuners, and graphics cards carefully they will all pretty much just plug and play. And the software is pretty easy to install if you carefully follow the docs at www.mythtv.org/docs/ and you *read every word*. If you don't do enough research (the lists are a good place to start) before you buy, you will have to slam your head against the biggest hurdles that people seem to run into when installing mythtv, namely hardware issues. The four biggies seem to be sound cards without full duplex support, graphics cards without xv support, tv-out issues (I use and external converter that works great) and tuners which auto-detect as the wrong type. Look over the lists, pick what people have been having good luck with, and go to town. best, cedar
