One of the major enhancements with TiVo desktop 2.8 is autotransfer, as this enables you to transfer complete folders from PC to TiVo. The folders retain the same name that they have on the PC.
Unfortunately, it appears that autotransfer cannot handle .mpg files (output from programs such as VideoReDo or TMPGEnc MPEG Editor).
These files will transfer fine as individual files but will not autotransfer. This effectively means that I cannot use autotransfer, since all my edited files are mpeg. Other file formats which will autotransfer OK include: .avi, .divx, .wmv, and .mp4.
Not many people seem to have complained about this problem, which surprises me, given that autotransfer, if it worked, is such a neat feature.
