#11020 closed Patch - Bug Fix (Fixed)
LiveTV-program guide unsuitable at an windows frontend

Description
With an windows frontend (WindowXP-SP3) in liveTV if I start the program guide with shortcut s (configured to show liveTV in the small window) liveTV stops for several seconds and audio is repeated that time in an endless loop (it's annoying because I've already setup the big audio-buffer, without it's worse, also in starting PIP). And this behaviour repeats at every move in program-guidegrid in vertical order (also on line up/down without move of the channels). I've done some investigation and saw,that the long interruptions were caused by the many myth-protocal requests for the free-recorders from mythbackend and that during this requests reading from the ringbuffer stops. So I decided to write a patch that caches the free-recorders from the backend in an vector at entering the liveTV-program guide because during the limited time the program guide displays the possibility the free-recorders change is low. With that workaround liveTV-programGuide shows up and is movable without interruptions in the ongoing program.
So now I provide the patch. Perhaps it could be helpful for some other people.

Recently I switched from fixes/0.25 to master. The patch also works fine. So I will attach it here.

Giving some feedback at the request of Jim Sitchnot (fyi - I have not applied any patches... I'm just running a version 0.27-fixes from a few days ago. This is on linux using vdpau (if that matters).
- Navigating between on-screen items without scrolling;
When I launch the guide within live tv, it actually launches pretty quickly, and stutters just slightly as it's loading. I see/hear 2 quick stutters usually at launching the EPG. I see 5 channels on my guide when it appears. It is center focused. If I move the focus up or down (without scrolling the screen), I get a slight pause(stutter) in audio and video playback. The movement of the "cursor" is very slightly delayed after my keypress, but not too terrible - maybe .25-.35 seconds between the time the up button is pressed and the channel focus above is selected. During this time, audio/video playback stops. If I navigate right on a selected channel in the EPG (without scrolling to the next page), it responds almost immediately and does not cause any playback stuttering at all. I can scroll back left to the starting position with the same results (no stuttering)
- Scrolling left/right on the same channel;
If I scroll left/right across the page, then I will occasionally (every 4-5 keypresses) experiences a slight stutter, but much less than going up or down.
- Scrolling up/down
Same behavior as #1 - longer stutter/pause. Also, the faster I repetitively hit up/down, the more noticable the delay in moving the focus and also the longer the audio/video pauses. For example, if I hit the up button 8 times in a row really quickly, the overall delay in response for the cursor to move and for video/audio to start again may be something like 4 seconds.

Work-in-progress patch for Master. Still some slight stuttering on an ION-1 frontend, but a vast improvement.

Attempted fixes/0.27 backport of the Master version. Compiles, but not yet tested.

Tested the version against 0.27-fixes.... here's my findings...
- Compiled just fine
- I see NO glitches in video or audio no matter how I navigate the guide (!!!! =D). Additionally, while launching the guide, I see not stuttering. Same for exiting the guide. Smooth AV playback the entire time.
- Guide navigation performance seems to be much improved as well, although not quite to the standards I've seen in commercial STBs. I will say though, that this is BIG BIG step in the right direction and makes leveraging the guide in Live TV a very pleasant experience.
Thank you Jim!
