I would love to burn my own blurays of each Classic Doctor's era (bluray doesn't have to be HD, that's a common misconception). Other then Tom Baker, you could probably fit each doctor's entire televised tenure on a single bluray disc.
Same here. In fact, I'm currently working on a project that is totally surrounding this very ideal, though, while I could just use the data straight off the DVDs, I'm trying to make them as visually lossless and as small as possible, which is a tricky fickle beast and has stalled as I'm waiting on feedback on a series of encodes (I did toy with the idea of posting them on Gal for a little feedback and almost did it).
I do, however, disagree with the final sentence from a realistic standpoint. While yes, you probably could fit an entire Doctor's tenure, you shouldn't for most of them as that would cause very low quality videos. It's also not considering the vast number of extras that really make the DVD collection what they are. I don't have accurate/reliable numbers so I'll avoid going into detail, but, going off the first season's DVD videos for episodes, total sizes of the Classic DVD era and my test encodings.....I'd say the following incredibly rough estimates:
| Doctor | Without Extras | With Extras |
|---|---|---|
| 1 | 1/2-2 | 2-3 |
| 2 | 1-2 | 2-2/3 |
| 3 | 2-3 | 4-6/7 |
| 4 | 2-3 | 5-8 |
| 5 | 1-2 | 3-4 |
| 6 | 1 | 1/2-2 |
| 7 | 1 | 2 |
| 8 | 1 | 1 |
| Total | 10/11-15 | 20/21-28/31. |
I've only included the serials that have been released in full (including animated episodes).
(Some estimates were close enough to the edge that I put /s.)
The next version of Blu-ray looks even more exciting. With an estimated double efficiency and double max storage space, that's an estimate 4-8 discs for the entire collection. Just a shame that it would be a good 5-10 years until it's got to a high in usage and even then, it won't be much due to streaming.
