The Roamio's hardwired to a Fios Quantum router as is the iMac I'm using. Using a Roamio plus with 3TB HD connected to network via MoCa. I downloaded the latest version of kttmg in order to offload files from a Tivo that's behaving strangely. I also notice that the transfers are slower on standby while being tuned to channels not received than when the Tivo is merely tuned to channels I don't receive. That approach does not work as well on the Tivo HD since the transfers are much slower thus it is more difficult to find time to transfer the recordings when no other shows are being recorded simultaneously. In order to circumvent this issue on my XL4, I usually only transfer when no other shows are being recorded. These sudden reboots have also occurred when I was transferring a recording while several other shows were being recorded on my Tivo Premiere XL4 so it's not only prone to Tivo HDs. From my experience, a reboot usually only happens for me when a show is being recorded at the same time though.

I'm not sure though since I wasn't at home at the time. The other unused tuner may have been tuned to a channel I receive. To give you some background I have a Tivo HD and it has only rebooted once while transferring a recording via PC at the same time another show was being recorded. I was wondering if anyone was able to find any success with this approach, or if it didn't really make a difference for them with regards to sudden reboots. I have been experimenting with putting the Tivo in standby mode while transferring recordings to prevent this from happening.

Since you can't always have all tuners on a channel you don't receive when transferring a recording, this makes it harder to guarantee a sudden reboot won't happen while transferring a recording via kmttg.
