For those wishing to use their computer for recording/watching OTA programming (Windows Media Center, SageTV, BeyondTV, etc.) or who already have a HTPC system , I highly recommend this Tuner:

You can watch one program while recording another or record two programs at the same time.
Thanks RonBoyd. A very interesting alternative. I'll look into it.
BTW, I did a little reading last night, and found out that RustyShackleford was correct. The Philips DVDR 3575/3576 is a Standard Definition (SD) machine, and not a High Definition (HD) one. So the DVDR highest output resolution is 720x480p, same as DVD resolution. It does have advanced pass-through that let HD signal goes directly to the TV, as long as it's not in recording mode.
Quote:
This DVDR has an active (amplified) RF/coax passthru that is, internally, separate from the tuner. The coax in/out loop delivers and slightly amplifies whatever signal is fed in, including hi-def TV (HDTV) in its native form, directly to your TV and other downstream components, even when this DVDR is off.
On a separate internal path, the incoming RF/coax signal is slightly amplified and fed to this DVDR's std def. (SDTV) tuner. This allows you to watch your normal HD on your TV AND record on this DVDR at the same time.
However, this DVDR... and ALL SDTV DVD recorders in North America... downrezzes the HDTV signal path that goes thru its tuner or line inputs so it can record in 480i as required by the SDTV DVD-Video standard. For watching DVDR channels or recordings on your TV, the downrezzed signal can be converted to 480p thru Component and HDMI, or converted and uprezzed to 720p, 1080i or 1080p thru HDMI, if desired.
If you want to RECORD HDTV video in its native hi-def on a standalone DVD recorder you don't have to rent, you'll have to move to Japan and change your name to Sokitumi.
