DD 1.5a hanged when using sheduled recording

[poppo]

Hi Yesterday i sheduled two recordings One 27 minutes long and 3 minutes after the first one second one (4 hours long on different channell)
The first recording started ok but when it finished then DD hung (noo eureka log or anything)
I Observed this problem on some channels while others work just fine (manual recording works ok for this channel no problems starting or stopping it )

which video codec do you use?

[poppo]

Here is a screenshot of my codec config (channels were SD channels)
--EDIT--
Buffer sizes are on default
MPG2 - 2MB
H264 - 32MB
--
AUDIO - 64KB

Video buffer 1KB

If there is a need i can upload stream samples from those channels

ps Im recording all audio tracks video and epg data

---EDIT 2---
Still with 1.5a
Today I was there when the recording hanged actually when that small grey box with blue bar appeared Video and audio played ok for 10 seconds than the entire app froze. Same channel with recording started manually has no problems at all only with sheduled recording

From tomorow I will use 1.5b
