Hello All, I'd appreciate a little insight from those more experienced here. After trawling through the vast number of posts on this forum looking for "thumbs backup" or some other boolean expression this has thus far not delivered any kind of meaningful information I hoped it might have.. To summarise what i believe to be the situation (after a lot of reading), 1, It is possible to backup thumbs data using MFStools 2, There was some work done on managing thumbs in S2 boxes in the US but this was dropped from S3 onwards (of no use for S1 - but an intriguing read) 3, It is not as yet been possible to interrogate the thumbs data to extract it in meaningful way to re-use it. I have already backed-up my season passes from the S1 TiVo which now live (reasonably well i might add) as smart guides on my alternative solution, however I was hopjng to be able to use the 11 years of thumbs data to create further smart guides, although it seems this may not be achievable. If anyone can correct what is posted above and point me to something I missed that would be very much appreciated and useful. Many Thanks.
