I'm starting to suspect you can overload the HDR.
I've had recorded programme playback picture freezing for a second or 2 before carrying on, a couple of occasions now, when I am doing file manipulation on the HDR via my laptop over Wi-Fi.
1. HDR is playing back a recording, whilst also recording two other programmes, all HD content.
2. Log into the HDR using Filezilla, and start to ftp 4 movie files (SD) across to my laptop for editing & viewing on my iphone.
3. When 2 files complete, use filezilla to select & delete all the 6 files on the HDR associated with the 2 movies in one go.
4. So, it is now playing back a recording, recording 2 others, still ftp'ing 2 large movie files, and deleting 6 files, all at once.
5. The deletions seemed to take a while until the Filezilla window "suddenly" refreshed. At the same time, the playback programme that we were watching also jerked a couple of times (I was multitasking on the laptop and watch TV at the same time 
), and Mrs savvy definitely noticed it (not good !!).
6. Interestingly, when we came to play back the programs that were also recording at the time, they had similar very brief glitches at around the time that I would have been doing the deletions.
I haven't noticed this doing ftp'ing & streaming to other devices, whilst recording/playback, only whilst doing all of them them, then also doing simultaneous multiple/large file deletions. Not sure if it appears that the processor is being overloaded, or if it is a disk I/O problem - or if it is just me 
Les.
