MPC-HC sound problem with DTV and tv stations names

Hi, i'm new here and I would like to report at least 2 annoying problems that started to happen at least 2 years ago, at least the sound problem.
When I start mpc-hc (after a fresh k-lite install) and i go to File -> Open Device... , it gives me an error, then i need to go to View -> Options -> Capture and change Network Provider from Microsoft Network Provider to DVB-T, apply and back to Microsoft Network Provider, then Open Device... will work fine, MPC-HC switches to Live and i can click Scan button to open Tuner Scan, i can click Start and the stations are tuned fast, i can see 2 problems: Quality and Signal bars are like 2/5 filled and the names of the stations that have accents are not displayed correctly, it seems like it cant process utf-8 in the station's names. Then i can click Save.
The next problem is just that MPC-HC can't seem to determine the audio stream codec, therefore no sound whenever the tv channel i use.
Here's properties page info...:
Video: MPEG4 Video (H264) 1024x576 25fps [h264]
Unknown [001]
Unknown [002]
Subtitle: DVB Subtitles [sub]
Unknown [Antenna Out]

I tried to fiddle with many options as possible even only selecting the other encoding than LAV but no joy.
I would like to help testing or sorting out this problem.

Please submit the bug report here, so it won't be forgotten:
