I have about 5 tapes I cannot convert as my S-VHS player (Panasonic NV-HS830) thinks they are VHS-ET. It's automatically picking this up and of course the playback is broken, because they aren't. Has anyone any ideas on how to bypass this?

One of the tapes, I managed to get past this by manually tracking to the point it lost the VHS-ET flag, but I've had no luck with the rest.

What is it seeing that makes it think it's VHS-ET?

Can you post some screen shots or a short clip, If it's reading it as S-VHS ET the image shouldn't be broken up it should display black streaks like a true S-VHS tape, Something else is going on with the tape.

There is no "VHS-ET".
- S-VHS ET, yes. (expanded tech, extended timebase, others retconned names)
- VHS-ET, no.

This can flash on/off when the tape is bad. I see this quite a bit on JVC decks.

I was not aware of any Panasonic deck having the feature.

You are correct, I missed the S! Here's an image showing the flag showing up with a standard VHS:

Here's what the playback looks like:
https://i.ibb.co/yN0HCN9/IMG-20200712-223404.jpg

Does anyone know what the machine uses to deduce the tape is recorded in S-VHS ET? There's no setting to change playback mode, it's all automatic, so I'm not sure what to do...

No that's not S-VHS ET signal, It's either the tape is erased, recorded on a badly missaligned VCR, a speed standard that the VCR cannot handle, or bad playback VCR. Don't worry about the logo, some JVC machines display S-VHS ET when they can't lock on a standard. You need a different VCR to find out what's wrong with the tapes.

From an issue I've had with dirty heads, I think it's more that if they can't lock on a standard, they're defaulting to S-VHS ET.

S-VHS ET was designed to record a S-VHS like signal on normal VHS tapes i understand, indeed trying to play this VHS tape on a different VHS VCR could help, one that would not have the ET feature, otherwise it really could be a bad recording
I however did find a notice on a JVC support page:

Quote:
Super VHS ET (Expansion Technology)*

A new innovation that puts higher quality within everybody's reach, this advanced function lets you record Super VHS signals on the more widely available VHS tapes**, so you can enjoy +60% better picture quality at the touch of a button.

* Only SP mode recording and playback is available for Super VHS ET.
** JVC's EHG (Extra High Grade) tapes recommended. There are some S-VHS VCR models by JVC and other manufacturers with which playback of an S-VHS ET recorded tape is not possiblee.

He doesn't have any S-VHS ET tapes, his VCR heads were dirty as he mentioned.

correct, and a normal vhs-vcr that doesn't have the S-VHS ET "feature" will play the tape without error, is my guess.

Perhaps, but not necessarily. Sometimes it just plays snow/garbage.

He said he doesn't have S-VHS ET tapes, S-VHS ET tapes are no different from S-VHS although at a lower quality, The luma frequency modulation is pushed slightly higher than normal VHS and lower that of a S-VHS cassette due to tape formulation limited magnetic performance. It will not play without artifacts in a normal VHS player, It will however play with less artifacts than a native S-VHS recording.

I was thinking that the S-VHS ET "detection" of this recorder is causing the problem, i do know from the other posts the tapes were not recorded with S-VHS ET.

I'm of this thinking as well. The majority of issues I've had with tracking are the player jumping around trying to figure out what it's playing. I've a Hitachi top loader from the 80s that allows you to manually set all the tracking using knobs. I'd wager it would play any of these tapes easily.

Unfortunately it's currently nonoperational due to a mechanical issue, so I can't check this. I know the playback from it is blurry as well (is this worn heads? can it be fixed?), so I wouldn't want to capture from it anyway.

I have a bog standard Sharp deck from the mid 2000s that I just can't get to at the minute. I've put the tapes aside the Panasonic can't handle and will try them on the Sharp when I get a chance. I've a feeling it's going to play them though.

No, not even close, If the VCR switches to S-VHS ET mode by accident (which seem impossible unless some leaky failing capacitors) it would still playback a VHS tape (it freaks out the AGC though), The opposite is not true.

I've put in crinkled tapes before, and ET blinks on an off in JVCs.

Yes, it happens on my VCR too, but it wouldn't switch to S-VHS ET on its own when playing back a stable VHS tape unless it has an electronic failure. Eric-Jan's idea of not playing a tape because it might be defaulting to S-VHS ET has no basis what so ever.

Was that ascertained?
If so, VHS tape is truly flawless, then deck error as you say.
