The best fit would be the original.  That listing suggests that the SE-R0297 will function with the D-VR610, and the codes for that are available at hifi-remote.com.  It uses NEC1 69.188 and remotes made by UEI should work using Video 1008  (21008 for remotes using 5 digit setup codes)

Cheapest would be the Comcast (Xfinity) 3DVR with red OK/Select button. Usually these can be found new on eBay for $6.  Or you could get a RCA RCRP05B  ($20 or less).  Either of these remotes can have individual buttons programmed to send additional functions, provided the basic setup code exists.  The RCRP05B can also learn signals if you have the original.
