Video recording issues (it jumps and the audio sto...

Question

Dear Support team,
I was very satisfied with my phone for a couple of months but nowadays I've an annoying issue with the video recordings of my Nokia Lumia 920. I've noticed in the past few weeks that there's a "bleep" or a "jump" in each video I take. (Nokia Camera software, Lumia Black, RM-821_eu_hungary_434)
It's very dissapointing because every video is let's say faulty at some point of the video.
For example please take a look at the following video at 0:34 where not just the video "jumps" but the audio recording also stops for a couple of seconds:

The interesting thing is that during the next 21 minutes it did not make any mistakes while recording.
Please take a look at an another example at 3:31:

If you're interested in debugging the issue I can send you somehow (by FTP or so) the original files as well.
I have got more videos which are like this and it was shown like this on the phone's screen as well so I've ruled out the possibility to have an issue while transfering it to my PC.
I'm assuming that possibly there's something wrong with the Lumia 920's RAM memory or with the 32GB internal storage drive, e.g.: let's say bad sector like on hard drives.
The phone recently had it's first freezing while I was reading my facebook the phone suddenly went black and restarted.
I still have 1,5 year warranty on my phone but I've bought ~150 km far away so I hopeI won't need to travel there and wait for weeks and to travel there again to get my phone back! What do you suggest?
Is it possible that it's rather a software issue not a hardware? Or should I return my phone to the retail shop or is there any downloadable software patch to correct this issue? Is this a known issue to you?
I've noticed one more thing: when I'm using my phone for e.g. like 10 minutes it's back cover gets warmer and warmer somewhere around the camera; I thought first it's because of the higher processor and battery usage but I don't think it's normal. The "heat issue" is also present while playing with a game.
Info: my battery lasts for 1,5 day or so by very moderate usage, is it normal? (4 times a day wifi for 5-10 minutes, max. 1 pcs one minute call per day)
Thanks for your help in advance,
Best Regards

Hi All,
I'm shocked about this device as you know I was disappointed due to the video recording glitches previously, but what yesterday happened is the worst I could ever imagine: I've recorded 3 videos and from this 3 videos 2 are unplayable even on my phone and on my PC, it gives an error message: "The video failed to play".
The 2 files can't be seen in the camera roll only by using Pocket File Manager.
I was able to copy all files to my computer:
WP_20140802_21_16_58_Pro.mp4 - 661 203 084 bytes - playable
WP_20140802_21_22_19_Pro.mp4 - 3939 658 131 bytes - unplayable
WP_20140802_22_13_59_Pro.mp4 - 3235 991 965 bytes - unplayable
To me these 2 videos are really very important, please help me to recover them! Please tell me, how you want me to send the files as they're, ~4GB each, by using Onedrive or how?
If this issue won't be solved I'm considering NOT TO BUY a Nokia again! Can it be a hardware related issue, e.g. faulty internal flash? Should I return the phone to the retail shop?
