The Sony products to which you refer, the HDR-SR1 and the HDR-UX1, are
AVCHD-format camcorders, *not* HDV-format camcorders (the subject of
the thread was HDV, not AVCHD).
All HDV products, whether 720p (19.7 Mbps) or 1080i (25 Mbps), use
MPEG-2 MP@H-14 while the two Sony AVCHD camcorders just mentioned use
MPEG-4 Part 10 H.264 AVC. All Sony HDV and AVCHD products record
1080i; none record 720p.
The HDR-SR1 records to a hard disk drive at a maximum data rate of 15
Mbps while the HDR-UX1 records to Mini-DVD discs at a maximum data
rate of 12 Mbps. Neither of these products record to CD media.
