Well I give up
Received the second MAG 537 in accordance with W*lm*rt's 90 day exchange policy.
Recorded 1hr 45 minutes of content to the HDD in SP mode.
High Speed dubbing that title to a Sony DVD+R 16x
on the second MAG 537 took the same 25 minutes.
That's exactly how long the first one takes to HSD that amount.
I don't know how you guys are getting 16 minute HSDubs on your older MAG recorders.I'd like to hear from other owners of specifically the model 537.How long does your Mag 537 take to High Speed Dub about 2 hours of SP content to DVD?
As for this second "newer" recorder. The Manufacturing date is September 2012.
The first one I got is November 2012
so the replacement they sent me is actually older.
I think I'm gonna send back the second one!
