ReadyNAS Ultra 6 Tivo Not Archiving -- KUID problem?

I have had a running battle trying to get consistent archiving from from Tivo (Premier XL) to ReadyNas Ultra 6 plus - for a while it seemed to mostly work but since July it only very rarely works with only about 5 successful archive attempts since that time, one as recently as Dec 2nd.

My Ultra 6 Plus is now running new firmware image. (RAIDiator-x86 4.2.19) which I updated today while trying to reset both the Tivo and ReadyNAS. I have rebooted both and launched several attempts of archive but same issues remain.

I have been searching the forum and see that others have problems with files not properly recognized as KUID. Noting these similar problems, but I did not seem to find a post with any solution I will try to state my situation here.

My logs show many many listings such as this today, each and every day it tries to archive:

[2011/12/20 18:01:10] tivo_utils.c:249: info: Modern Family (Two Monkeys and a Panda) is no longer KUID (expires 2038-01-19T03:14:00Z). Skipping.

this entry is repeated for virtually everything on my Tivo currently. Very strange, but today was the first time I looked at the Tivo log as I did not know one existed until seeing the other posts I simply thought the ReadyNAS and Tivo did not connect at all.

I checked the Tivo and this program is clearly marked KUID (Keep until I delete) and should be archived. I managed to get some shows archived on Dec 2nd and Nov 25th but no matter what I mark KUID on the TIVO box does not seem to matter - the archive simply skips over it.

I have RAIDar 4.3.0 and all "lights" on the RAIDar are Green. I can also see and play any archived files on Tivo or my mac. Just can't seem to add any new shows.

Under the Streaming Services tab / ReadyDLNA it shows v1.0.22 not sure if this is current or how to update?

Any other info needed to troubleshoot?

Any ideas on how to fix as I am running out of disk space on the Tivo?

Thanks!
