I read somewhere on the net that HDMI-USB Video capture 2.0 (whale) on ms2109 can be flashed with eeprom from HDMI-USB Video capture 3.0 (whale) and the quality will improve. But I never found the merged firmware. This is not a review, but rather a report on the experiment done. I hope he helps someone. Several cards were bought for the test.
Merged eeprom from 24c16 (2 cards), but since the first card was 24c08, there was not enough space for filling. I found 24s16, poured it in, everything worked, the quality got better.
video 720p max
video 1080p max
I post 2 firmware from the 1st and 2nd cards, you never know who is interested in digging.

There are no guarantees that you will succeed.
