Yep! This is good. As previously mentioned, aspect ratio switching occurs about 6 second early (both 4:3 to 16:9 and 16:9 to 4:3) on Channel 4 (UK, QAM 64). Are there multiple signals available from the demux? Perhaps there is a standard length of time / number of frames that broadcasters send out the signal in advance. It would be great if this could be sorted. Coming in to the programme is OK but leaving for an ad break distorts the programme picture for 6 seconds.

When exiting from the options menu, the TV switches aspect ratio to 4:3 then back to 16:9 quickly. No great shakes but if it's obvious why, it would be nicer for it not to happen.

Setting the mvp option to 16:9 now allows me to see all of the picture of all recordings / channels. Previously, the image was displayed as 4:3 image with left and right portions cut off. The TV is not however switching to the right mode via the signalling in the SCART connector automatically. I can force my TV to the right aspect ratio so dongle 0.0.10 is a great improvement but still not working fully in this 'aspect'.

There are two means of signalling aspect ratio to a TV. One is to place a specific voltage on the signal pin of the SCART. The other is data embedded in an out of view line of the picture. (From memory, I think it may be line 23.) Given my TV remains locked firmly to 4:3 from the mvp, I assume either the SCART is asserting 4:3 and overriding the video signalling or that this signalling is not being encoded by UK broadcasters on digital feeds. I know my TV handles line 23 switching because it switches aspect from a VHS source via UHF (aerial) input and I am quite sure that UK broadcasters are using this method.

There are also a few different aspect ratios that can be signalled. 4:3 & 16:9 are the most commonly known but BBC are fond of 14:9 as an effort to compromise between both conventional and widescreen viewers. My Panasonic TV will switch to 16:9 on receiving a 14:9 signal.

Given that selecting Resume on a recording with no resume point appears to have identical effect as selecting Play, why bother with all the extra coding in looking for resume points?

I reckon we should avoid too many user options. You can end up with a thousand things that can be set that if the configuration gets corrupt, gives the users hours of fun reconfiguring. As a programmer, I always want complete control to tweak my devices slightest nuances but that is not actually good design for end users.

On selecting a recording, a menu offers these options; Play, Resume, Summary and Delete with Play being the default option. I find that I mostly want to resume replay. I would like members to discuss what they feel should be the default action here and if a consensus for change is reached, request Chris consider making this change.

I have made the very simple change to vrecordingmenu.cc to make resume the default action on my installation which has made my device work as I prefer.

I know this is trivial but suggest such things can be discussed and sorted quickly and it is best to establish a preferred operation early in development rather than change it later when a large user base has been established (This excellent work deserves a huge user base!)

Great work! I have been working toward doing this for a while and am glad you have started it. (Saves me a lot of work.) Looking good so far and with all (mostly) the same goals as I had.

It would be good if one could mount an NFS share on the MVP to assist with testing and developing but I couldn't do that with your latest dongle. I will try with another dongle when I get home but could you add this facility? I have not managed to get a working cross compiler yet which is why I still haven't produced ANY code for the MVP! When (if) I do, I'd like to be able to try a few things which would be easiest if the compiled object code could be run from NFS. I couldn't think of a way of transferring a file to the MVP.

Keep up the good work and I look forward to assisting where possible when I have a working development bed.
