Stange Behaviour handling pre padding on system with 3 tuners

[Handy.Man]

Hello,

I have a Win7 64bits computer with
- Hauppauge WinTV-HVR-2250 Dual ATSC Tuner showed as Hauppauge WinTV-7164 BDA ATSC/QAM Tuner
- Diamond ATI Theater HD 750 TVW750USB TV Tuner USB ATSC showed as a ATI BDA Digital Tuner
I have enabled Use backgroung recording and Use out-of-porcess digital recording

I sometimes have strange problems when i update a recording and change pre/post padding. Most of the time it works fine, but it will sometimes shuffle channel around on the tuner for no 'apparent' reason.

Earlier in the afternoon, I program a show to start on channel 17 at 19h00, update to add 1min pre-post padding. I also check to see if the show on channel 2 scheduled at 18:30 has 1min pre-post padding. I may have update that recording for 1min pre/post padding

At 18:29 3 shows (ch 2, 6, 15) are recording and it did not stop them to start ch 2 with 1min pre padding, no tuner are available and the recording will start at 18:30 instead of 18:29. However it was already recording on channel 2 on tuner24, it should have been able to grab and pre pad the show, instead it started recording on tuner26.

This happen on occasion when instead of keeping the tuner on the same channel, NextPVR will get confused and record 2 channels on the same tuner!, basically killing the one already recording by tuning to a another channel.

This happenned tonigh at 18:59 when it started recording 1min pre-padding on ch 17, killing the one on ch 2, however there was 2 tuners available at 19:00???

When I look at the log file, it seems to check only 2 tuners.
