It might not be the receiver that's giving up on the signal when this happens but your TV. Your TV's legacy inputs, composite and S-Video are more likely to be tolerant of the bad timings that occur when fast forwarding.
For what its worth, my AV receiver (HTR-8063 aka RX-A1000) doesn't seem to have a problem with fast forwarding a VHS tape, but my TV doesn't like it if I use its component video input when I do this. The composite and HDMI inputs work fine.
Like Sven37 said your only chance of fixing this problem in the receiver is with playing around video processing options. Turning them on might actually help as well. My AV receiver is actually converting my VCR's 480i video to 480p over HDMI because my TV HDMI input doesn't support 480i. That may be forcing the receiver to fix the timings into something the TV will accept.
Thanks for all your replies. I really don't want to connect the VCRs and the laserdisc direct to the TV/Projector as the RX-A3010 video processor is great and the image quality is very good.
I made a some tests with three different TVs and one projector using HDMI:
1) When using an external TBC, it solves the problem. But this is a very expensive solution as it will need one TBC for each composite video device.
2) Turning the video processing off, makes the display blink black for a second e the image appears again. With video processing on, it takes about 1 minute to the image appear again.
3) Used a chinese composite to HDMI converter and it works flawlessly, but the image quality is not as good as the RX-A3010 processing.
I think it is really related to the analog to digital conversion, but RX-A3010 specs informs that it has a internal TBC!!! So why do we need to use an external TBC?
Maybe it is a software/firmware issue. I am telling you that, because I had a RX-Z11 and this receiver was not able to display blacker than black images. I sent a lot of emails to Yamaha asking for this. They always said thay it was within specs. So I got the service manual for it and made a microcontroller code to change the I2C register of the video processor in real time, so it was able to pass blacker than black images!!!
After two years, Yamaha finally released a firmware that was able to pass blacker than black!!!
Just for the record: the RX-Z11 upconvertion was perfect!!!!
So maybe if I get the complete service manual for the RX-A3010, I could write a microcontroller code to set the video conversion chip to do the right thing.
Maybe other suggestions?
