Thank you for posting your query in the Community. By "vcr_timer", do you mean timer recording? The recording options are available through the guide/recording. Perhaps, you may want to elaborate your question so that we can look into providing more accurate information.
Rogers is spending little/no time/effort on NextBox features. They are concentrating on IgniteTV (IPTV), their latest offering. I believe the chances of them "bringing back" the VCR timer to which you refer are zero.
I'm not sure if you're talking about the VCR timer, that used to let you record to an external device like a VCR or DVD Recorder, or if you're talking about a "manual timer", much like you used to set on a VCR with a start/stop time. However, in either case, I'm pretty sure Rogers will not be implementing those on Navigatr firmware.
Those are available on SARA firmware utilized on the old SA8300 PVRs, etc, however, those will be phased out in the coming years as IPTV replaces everything on Rogers, including Nextbox.
I'm not sure which Nextbox you refer to in your initial post, however, if you have a PVR like the Nextbox 2 (Model 8642) or Nextbox 3 (Model 9865), you can record onto these first, then "copy" the recording to the recorder by hitting "play" on the PVR and "record" on the recorder simultaneously, at a convenient time, utilizing the same connections (usually composite video and analogue audio) to the recording device.
Not many people have a need for this any more, hence the lack of the feature on the new firmware. For example, the new IPTV boxes (and a lot of new equipment) don't even have that type of connection any more - only HDMI.
