One of the most useful SPS backdoor codes for me has long been SPSPS (Select-Play-Select-Pause-Select) which clears the play bar quickly when using trick play functions. Unlike all other SPS backdoor codes, since the introduction of "Pause Ads" it has been made increasingly more difficult to enter this code. The only reliable way to this point was to play a showcase video and enter the code while it is playing. That is a sure fire way to enter SPSPS with remote and have it stick.
Enter the Mini which of course doesn't have showcase videos and hence apparently no reliable way to enter SPSPS. I tried again and again to enter SPSPS with regular Peanut remote with the Mini but couldn't get it to work. Another strike against the Mini.
However, playing with it some more last night I found using the kmttg RPC Remote macro while playing back a recording seems to work very reliably.
So for those (apparently few) people that love the SPSPS code know that there is a way to enable it with the Mini despite lack of showcase videos.
(Also like for regular TiVos this backdoor is not sticky and needs to be re-entered upon reboot of the Mini).
