Thank you for viewing. The SD-P75DTW has a built-in one-seg tuner and also supports one-seg recording to SD memory cards and SDHC memory cards. One-seg recording is possible even during DVD playback, and scheduled recording can be done using the electronic program guide or by specifying the date and time. It also has a "recurring recording" function that allows you to record specific programs every time. You could watch one-seg TV and record with the included antenna, but it was unstable depending on the location. I will also include an initialized SD card. DVDs can be used without any problems. The battery has been removed due to wear. It can only be used with the power supply. There is discoloration due to aging, and while there are no noticeable scratches or stains, there are some fine scratches. Thank you for your understanding.
