Well, it appears that I am not the only one who is having this problem. Multiple other posters on this board are complaining about the exact same thing.
Also, people on the tivo.com forum are reporting the exact same problem.
One person on this website named figmund suggested a quick, easy workaround, and it works great. I went into kmttg and clicked the box "use java to transfer shows instead of curl"........ and presto, problem solved.
FYI...... figmund has posted on this board a total of 3 times since 2003....... he/she should post more often!
I am guessing a bit here, but evidently the Tivo company has done something which has screwed up transfers for their users. Perhaps they implemented a new firmware upgrade which contains some sort of bug?
