I own a Toshiba XS34 and my father want to get a Sony HX710. I read the user's manual that I downloaded from the Sony website and found some features that sound quite limitating: 1. Cannot record in 16:9 mode on DVD+R, +RW and +R DL 2. When using the time shift function, there cannot be less than 1 minute difference between the recording and the live program. On the Toshiba, you can be only 10 seconds or less behind the live program. I also noticed an interesting feature missing from the Sony: there is no PIP function that I find very useful on the Toshiba. I might not have understood the manual correctly, so correct me if you have any experience with the Sony (510, 710 and 910 share the same manual).
