How about an option in each member's account to specify the default recording quality. It would save those who record SD when there's a choice from having to change the quality to 'Prefer Std Def' every time they set a series recording.
Or better yet, automatically set the quality to the type of channel that the series is being set on:
* If the series is being set on a HD channel auto set it to 'Prefer High Def'.
* If the series is being set on an SD channel auto set it to 'Prefer Standard Def'.
This way the quality setting is more foolproof and ex TiVo and Foxtel users won't keep complaining about IceTV doing the wrong thing, like recording the ABC News on the wrong channel. i.e. Complaints like "If I set a series recording on ABC1 I don't want it to record on ABC24" and "I don't want to need to learn which channel is HD and which is SD".
