I've now tried my 3rd type of filter/converter, the MCM Digital Video Stabilizer for VHS tapes... nice metal box, runs dead cold, and now comes with 9V battery installed with 2000-hr life.
I used my Philips 3575 that had previously copied 9 of 14 of my comm. movies without a filter/stabilizer. I confirmed CP on one of those that didn't copy before by getting an E25 Error without the stabilizer, indicating MV protection, then confirmed stripping by copying twice from VCR to the Philips 3575... backup copies for my personal archive, of course. Viewed HDD copies in their natural 4:3 aspect on 32" Vizio 720p LCD. I also viewed in Wide aspect just to see the effect of stretching... not bad at all, just a little softer, as expected, but very watchable.
Edit: I just checked my power adapters for the HDMI and Component converters discussed previously, and they fit the jack on this unit, which can be used with an optional 9V adapter. Output power on the other adapters is 5V 1A. This unit's power usage spec is 1.8mW operating and 0.5mW in standby (it's activated by video sensing). Wonder if those 5V power adapters would work???
I recorded first in 3-hr-LP rec mode (by mistake), then again in 2-hr-SP rec mode. The LP copy is about as good as the VHS source, as confirmed by my very fussy wife/CEO.
She also confirmed that the 2-hr-SP copy was slightly better than the VHS original, esp. in the black screens or black objects. As I found with all my tape copying, the stabilizer didn't affect my 3575's ability to make solid, full-screen blacks more uniform and preserve the details in black objects like hair or clothing.
Of course, that ain't sayin' much when compared to a HDD recording from a digital HD channel by a DVDR user who forgot how "bad" the old days of tape were!
I have to assume that people who recently came from or are still in the VHS/analog realm would think both copies were "outstanding."
