This is what doctor sony said about which video8/hi8/digital8 sony player is the best:

DCR-TRV520 is the pinnacle of Digital 8 tech and it's downhill from that model (top of the line series was the DCR-TRV820 with a built in printer).

So we have some idea for Digital8. Anyone want to add about Video8/Hi8 players?

I don't know a thing about analog or digital camcorders. But with any video hardware, I know at least enough about video in general to not make the assumption that all models are equal in all respects.

Example: my first premium VCR was a 1990 Sony HSV-585HF. Real workhorse, loved it. Two years later I tried a new version of what appeared to be the same player. Forget it. I returned the new one, used the old '585 almost every day for 9 years, had it rebuilt at considerable expense 7 years ago, and still use it today. Never saw another SONY consumer VCR again that could work as well.

Thanks again sanlyn, I guess it was just that a list of the better camcorders wasn't compiled. Sounds like the DCR-TRV520 is the best Digital8 camcorder/player out there. Guess I lucked out that my parents just happened to have one (although it needed repairs/cleaning). Wondering if that's also true for it's Video8/Hi8 playback or if someone can mention whether there's a better model out there.

I've always been under the impression that any Digital 8 camcorder would work the same for transferring Digital 8 content. It's just moving 1s and 0s over the firewire cable, so I'd expect that any functional Digital 8 camcorder would be "the best". I'd imagine that the Digital 8 gear varies a lot though, in its ability to output analog content from Video8 and Hi8.

I just recently spent a lot of time with google trying to work through the who's who of 8mm cameras to see what I wanted to use for my home video captures/transfers. I had a DCR-TRV310 that we bought new back when I was a kid, and it did really well with the digital transfers. For the analog stuff, I had found some postings stating that the newer models (up to a point which I believe was the DCR-TRVx40 range) had better circuitry/chips for processing the analog signals. I needed something newer anyway, since my DCR-TRV310 didn't have TBC or DNR built in. I picked up a DCR-TRV740 which has TBC and DNR, and it works great for analog captures.

IC5 -
Here are details for my 3 main units:

#1
20040601xxxx
Either Cypress (manufacturer) or AVToolbox (rebadger) defaced all the chips. You cannot read any of them. The chips appear to be sanded down, and some sort of gray powder substance was left (possibly the dust from sanding).

#2
20050205xxxx
IC1 = SAA7114H
IC2 = CY37064VP44 (FPGA?)
IC3 = KCL KT88V422SA-2533, 0411-BS
IC4 = KCL KT88V422SA-2533, 0411-BS
IC5 = SAA7129H
IC6 = LTB-100 V2.0 A0412
IC7 = 24LC02B/SN0425 (Microchip brand?) EEPROM - still in production 2018
IC8 = Sanken 424 347, 8033JD

#3
20060705xxxx
IC1 = SAA7114H
IC2 = CY37064VP44 (FPGA?)
IC3 = KCL KT88V422MA-2533, 0537-BS
IC4 = KCL KT88V422MA-2533, 0537-BS
IC5 = SAA7129H
IC6 = LTB-100 V2.0 S0605
IC7 = 24LC02B/SN0553 (Microchip brand?) EEPROM - still in production 2018
IC8 = Sanken 5D2 618, 8033JD

The SAA = Philips/NXP
CY3706VP44 = in-house chip by Cypress, and rebadged by some no-name Chinese companies

I can find almost zero information on KCL. I believe it may be a Chinese no-name rebadge of somebody else.

My "IC6" is not labeled as such on my 2005 unit. It skips from IC5 to IC7, and this chip falls between them.

The main difference appears to be:
- IC2, CPLD/EEPROM, Altera vs. Cypress (not same Cypress)
- IC3/4, KCL vs. AverLogic
- IC6, V2.0 vs V2.1 vs V2.2

I doubt that the SAA7129 or SAA7114 changes much, if at all, and are simply rebranded for the date it was made. NXP = Philips = Trident, in terms of the chips. Possible, but doubt it.

I doubt versions of IC6 does much. Perhaps, but probably not as likely.

The culprit is probably AverLogic or Altera/Intel. However, the issue looks to be the frame sync, specifically the frame buffer. So whatever chip controls the framesync is probably the dud.
