In Canada, almost the last DVR in the big box stores for sale is the Toshiba DR-7. I rbought one two months ago, since it is the only DVR left for sale in the big chain stores in Canada.
I really like it! It passes thru S-video, and has several other advantages:
1) The DR-7 has no trouble with copy protection on Bell in Canada
2) It upconverts 480i sources like a standard cable box to 720p/1080p !! Most recorders just upconvert DVDs, not other sources.
3) If you use DVD-R or -RW, the DR-7 records letterbox using the full frame in the 480i recording (if you record on other recorders or use DVD+R then most recorders and the DR-7 record the big black bars on the top & bottom and just record black in the top and bottom areas...)
So when you playback this recorded DV, it will upconvert from 480i and give you the best quality.
4) The DR-7 records DTS, PCM, and Dolby surround audio tracks at the same time.
