Not my two DVDRs.

On separate DVD discs I recorded a TV program on both the Polaroid
DRM-2001G and the Insignia NS-DVDR1 at the poorest resolution - which
is 6 hr for both units(*).

I then opened each VOB directly in both GSpot and BitrateViewer
(latest version of each). Here's what I found:

GSpot:
Insignia 6-hr: MPEG-2, 352x480, 1460 kbps.
Polaroid 6-hr: MPEG-2, 352x480, 1622 kbps.

BitrateViewer:
Insignia 6-hr: MPEG-2, 352x480, 1379 kbps.
Polaroid 6-hr: MPEG-2, 352x480, 1529 kbps.

So it appears that MPEG-1 is a thing of the past with the newest codec
chip. That could explain why the 6-hr resolution looks the same as the
1-hr resolution on my 19" RCA TV.

(*) You can't use alphabetic designations for resolution on DVDRs
because they mean different things to different manufacturers. For
example, the Polaroid calls its 6-hr resolution "SLP" whereas the
Insignia calls its 6-hr resolution "EP". There is no "SLP" on the
Insignia and the "EP" designation on the Polaroid means 3-hr
resolution. You have to use the hourly designation.
