    S-VHS VCR #1 - 2D-Y/C Mitsubishi-type enhanced comb filter, DNR, TBC

    or

    S-VHS VCR #2 - 3D-Y/C comb filter, DNR


    I guess my question is whether having a TBC with "lower" comb filter will give better video playback than having a better comb filter without TBC. I currently have Sharp VC-S100U (VCR #2) and I was wondering whether the Mitsubishi HS-U778 (VCR #1) will give a better video. Thank you for your expert advices.

    They are for different purposes. The comb filter is for separating the luminance (B/W) and chroma (color) signals - so that just reduces some artifacts. DNR reduces noise in poor cable signals and the TBC reduces jitter from mechanical VCR signal. I'd say a 2D comb filter is good enough for its purpose and you gain a lot from the DNR and TBC features.

    So you are saying that 2D comb filter with DNR and TBC will be better than 3D comb filter with DNR but no TBC? Would TBC give a noticeable difference in video playback? Thanks.

    P.s. I thought DNR reduced noise in all video signals that are outputted by the VCR, not just cable signal. Am I mistaken?

    Yes a TBC with a VCR helps a lot, I had a JVC SVHS model with an interla TBC and it eliminates jitter. Unforunately that unit's power supply burned out last year and is too expensive to get fixed so I am using an older JVC SVHS without the TBC and I notice the quality difference! You can also buy external TBC units separately to use with an existing VCR.
