Recording (toshiba dvr player se-r0265

Number SE-R0265 is not a Player. It is the model number of the Remote Control for a player.

However, your question is somewhat generic for all Player/Recorders. First you must use good original manufactures DVD media for recording. TY (Taiyo Yuden) is the Toshiba recommended media in many of its manuals. Verbatim and Fuji are also very good. They are more expensive, but very much worth the extra cost in reliability and headaches. Also, some older recorders will have trouble recording/playing back/finalizing newer 8X or 16X faster media. Try to by 4X and slower media if you are having problems, even with the three recommended above.

Second, DVD-R or R/W media has to be 'Finalized' before it can play on other recorders. DVD media do not. Try using DVD media if you continue to have trouble. Also, there are two recording/format types you can choose to record with on your DVDR Recorder, Video and VR, on -R/W media. Video is automatic Video format only on DVD media and do not need to be formatted (I think) before use or finalized after done recording.
If you are still having trouble using -R/W DVDs on other players, Try DVD DVDs in Video Format.

Finally, Toshiba is know for DVD media sensitivity. Many of their recorders have Firmware upgrades. Be sure you have the latest by looking in your manual to find your Firmware Version, then check out Toshiba's support site for any upgrades. But, start with good media, finalizing -R/W media, using Video disc format, then using DVD media, in this order.
