vista media center (sp corrected) works just fine with analog tuners. and with dvb-t tuners.
and even dual dvb-t , or dual analog.
you sir, are referring to software tuners. those junky bt878 (and other silly chip) based devices.
vista media center, and mce2005, and every version of microsoft's lovely media center program has always had a requirement for a hardware mpeg2 encoding capturing card, if using analog sources. like hte povr150/250/500 range from hauppauge, or the ehome wonder, ehome wonder elite, theater 550 pro from ati...they are all analog tuners, to tune analog frequencies, for which vista/mce is designed.
and what is this channel changing you are trying to describe? it is so wrong i cant even figure out where your logic is faulty.? you can switch channels with it always...heck, either you
1) use dvb-t, in whcih case you press ch+ and it changes up a channel
2) you use plain old analogue, in which case you press ch+ and it changes a channel
3) you plumb your dstv/mnet through the analogue tuner, in which case you press ch+ and it sends a signal to the irblaster which sputs out the correct codes so that you decoder changes channel.
what part are you referring to?
thankx
