The FF cards have a maximum resolution of about 720x576, 50 fields per second
interlaced. This is clearly not compatible with the resolutions and
progressive nature of many HDTV sources.
Another reason is the bitrate.. the FF cards generally max out at 10Mbps, and
HDTV streams often exceed this.
I would also expect a lack of decode buffer space on the FF cards, so, even if
there were sufficient ARM CPU power to decode the stream, you would get no
higher definition than you current experience, leaving the whole exercise
rather moot...
So, stick with a powerful CPU+software, or wait around for an 'HDTV hardware
card' whenever that will arrive....

I am curious. If I have a FF card as device 1 and a budget card as device 2, Astra HD and Euro 1080 marked with a CA PID of "2" in the channel.conf, running VDR 1.3.15 with the HDTV patch, what exactly should happen, if one of these HDTV channels is selected?

Wouldn't it be possible, to perform a software downscaling, so that the signal nevertheless can be output over the FF card, so that at least it would be possible to have a live watch of that channel?

if you can downscale it you have already decoded it
