Playing around with a "recreate the TiVo UI" HME app because my wife hates the Guide (and emboldened by a recent post by somebody else who wants the guide improved). First, a little while back I was messing with Network Remote UI... ran it against my keycode-exposing HME app and found that a lot of mystery keys are available in V49 as rawcodes. This includes the Back button. So I can catch somebody pressing the Back button if I run as a V49 app, then when I see a keypress with code of 0, I just check for a rawcode of -7680 Others available that way include CC_ON, TUNER_SWITCH (which isn't available through anything currently), ASPECT_ codes, VIDEO_MODE_ codes, etc. I think you can get anything that doesn't teleport you out of HME. Second, since I'm messing with LiveTV I noticed QuickMode is available on my mini when watching LiveTV, too...so knowing that it's advertised as 20% faster, I tried setting my "livetv:" stream's speed to 1.2 and voila, quickmode with sound in HME. I haven't experimented with other speeds that might be "alternate" quickmodes yet. I also haven't experimented with using it on other video streams, but it seems likely it would work. I have also noted that a rpc connection to a mini reports TunerState of the host DVR (and nothing explicitly identifies which tuner the Mini is using aside from the fact that it wouldn't be the foreground one... perhaps it's always the first background one?). However, Network Remote does report the correct channel in use by the Mini, so I'd just have to identify this is a mini, check the network remote status, and cross reference with the rpc tuner state. I haven't yet figured out how I'd make channel changing work from a mini, though, since somebody reported that SETCH/FORCECH don't work against a mini (I want to experiment with explicit SETCH using a channel the host is already tuned to, other than that I don't know what to do). As far as I see, there is no RPC command equivalent to SETCH and FORCECH. Do you agree? It would be nice to not have to use Network Remote at all, except I'd probably still need it for Mini status. Finally, I THINK I figured out how I could easily create a Youtube viewing app for HME. But I figured it out after the update that broke MP4. So if TiVo ever fixes MP4s, I'll try out my method and hopefully have Youtube working in EWz again.
