Thank you for the info!  2 more questions for you:

1)  You mentioned you use both the PVR-250 and the pcHDTV.  So the
pchdtv2000/3000 gets HD OTA, but does not replace the PVR-250 for standard
TV?  To get both you need both cards?  Or are you using 2 so you can have 2
tuners to have more simultaneous watch/record options?

2)  <<Component video is an analog colorspace signal format. Just a step up
from SVideo really.>>  But svideo is still standard NTSC resolution, isn't
component video HD resolution?  

Thanks agains for all the insight, it is very helpful.

Oh it's worse then "encrypted". Funny thing about Time Warner... They don't
use _any_ standards for _anything_ ... "Road Runner" their cable internet
service, doesn't even adhere to DOCSIS standards, that they paid millions to
help create.... Their "digital" channels don't even come close to using ATSC
specs. They are most likely extremely low bitrate mpeg2 or perhaps even
mpeg4. You can see compression artifacts all the time when watching
"digital" and "HD" stations will Time Warner. They don't care about quality,
they just want to pack in as many stations as possible. Cause saddly...
there isn't many people that are going to notice the difference...

I have time warner.... I use S-video into a PVR-250 or btv capture with an
IR-blaster to change the channels on the box. I also have a pchdtv-2000 card
in that computer that gets me my OTA HD stations.
Without support for firewire, I think that's the cheapest/easiest/most
capatible way to do things right now.

Component video is an analog colorspace signal format. Just a step up from
SVideo really.
