I have an old TV Tuner card by AverTV that uses the CX23102 chipset, and it's very bad for VHS if you don't put a TBC in between. It doesn't tolerate time base errors.
That Io Data device is a clone of this: https://www.yuan.com.tw/products/cap...rnal/pd652.htm
It even uses the same drivers. I have another one from them that has HDMI and SDI inputs as well, and the composite/S Video decoder is still the same (TW9910). Somehow it performs differently on SECAM, maybe due to some internal configuration.
It's very good for PAL. You'd only need a TBC in between if the tape is really bad, or LP playback.
