For me personally I am waiting for the Ideal solution, there is something weird about UK HD that seems to make it more CPU intensive than our european counterparts !! There are only 2 programs worth considering at the moment for use with a TT S3200, they are DVBviewer and ALTDVB !!
1) DVB viewer is excellent however it strugles to decode UK HD perfectly smoothly it is so close and yet not quite there !! hopefully soon to be fixed.
2) Alt DVB again excellent, no where near as many bells and whistles just a straight forward excellent ppiece of decoding software, which using the same HD codec (Core AVC) as DVB viewer does an excellent job of decoding UK HD and apart from the odd software crash. It allows me to watch BBC HD flawlessly unfortunatly this s/ware DOES NOT currently support using a viewing card, so no SKY here. however the author has assured me the next release will support viewing cards !! this is good news
I have a 3.2GHz P4 prescott Oc/d to 3.6Ghz
and an ATI X1300 with 512 MB ram !!
