I've talked to Tivo twice - and poured over threads about recording quality. I see people saying that digital channels (including sd channels) will just record at the quality and file size they are transmitted - that there is no such thing as the ability to select basic, medium, high or best quality. I see that people have said that if you're using a cable card and getting digital channels, that you simply get the file size that is transmitted. However - my experience is different than these claims. And the impact on me is huge. I have bought two Tivo Elites (now called XL4). I like to keep a lot of recordings - and would not have the space to store all of it if it were in high/best quality sd or hd. For a couple of years (after Comcast became all digital - and with cable cards the whole time), I have been recording series that I'd like to keep in sd (on basic or medium quality). Each 1/2 hour sitcom (for example) would be about 350-550 MB. This quality and file size would allow me to get the 2774 hours of sd recordings that Tivo claims you can get with a 2TB drive. And I wanted that many hours of recordings. Last month, everything changed. At some point in December (between the 4th and 11th) - I think after the fall update, I noticed that my sitcoms were now 2100MB in size. When I first went to Tivo Desktop plus to pull it to my PC (for commercial cutting with VideoRedo) and eventual storage, I noticed that some of these 1/2 hour sitcoms were over 2GB in size. At first I thought that the fall update might have reset my season passes to record from the HD channels. So once the holiday busy-ness was over, I re-did some of my season passes. Then discovered that they were definitely recording on the sd channel (ABC, NBC, FOX,, Nick, TBS, BBC, G4 - as far as I have noticed, this is occurring on all channels) - but were recording as highest quality and largest file size. Then I thought that perhaps the fall update changed the recording quality to a default of highest quality. I have a Tivo premier and went in and made sure to set the recording quality on basic. I went to change the recording quality on the two Tivo Elites (Tivo 4's) - and saw there was no option to choose recording quality on these. I called Tivo twice - both people were surprised at this and unaware of it - but both checked. One said what I've read here - that digital channels will record at whatever quality/size they are broadcast. Tivo has nothing to do with that size. But - again - until mid-December, I was able to record sd channels at different qualities and file sizes across all my Tivos (Tivo 4, premier and HD). The other Tivo rep said there should be some software change they can make and he'll escalate my issue bc. I would not have bought the last Tivo XL4 if I'd only be able to record about 500 sd hours. It seems that none of what I've read or heard reconciles with my experience. I have a Tivo Elite I got in April, 2012. It is filled with sd recordings I've made. I have one hour dramas (like Parenthood) with a file size of 990MB up until Dec, 4, 2012. After that, an hour episode (same channel) is 2100MB large. It's also striking to me that both 1/2 hour sitcomes and full hour shows in sd are both 2100MB. Same with Dr. Who (BBC) - one hour episode was 990MB until Dec. 6, and 2100MB starting on Dec. 7. December 7 is the date that I got the fall update rolled out to my Tivo's. Various sitcoms were 350- 650MB range before mid-December. Now all my 1/2 hour shows are 2100MB. This is not a big space saving above HD, where a 1/2 hour show in high definition is in the 2600-2900MB range. Since this change has occurred across all networks, I do not think it's a matter of the networks changing the quality/file size of the shows they transmit. And I definitely was getting SD shows recorded in much less space before December. So I think I am asking for a few things: 1- a way to understand why this change occurred. These channels have been digital all along and I've used cable cards all along 2 - is it possible that Tivo software could reverse this change? 3 - managing my recordings is already taking too much of my time. I have been learning to use VideoRedo more efficiently and do batch managing to remove commercials. I like to save my videos as Tivo files - so that the meta-data is kept - and when I transfer the edited shows back to my Tivo, they group together in the same folder. For those reasons, I want to keep saving my edited files as Tivo files. If I do that, is there an easy way to reduce the file size? I know if I create a DVD (which I haven't done in a couple of years and don't quite remember), I can reduce file quality/size. If there is no way to still record shows with a smaller file size, is there an easy way to change the size later? I hope my questions are clear. I know there are many on these forums that would not want to record in reduced quality/file size. But I've also seen some who share my concern for conserving space. Thank you for any input, similar experiences, suggestions, etc. Lynn. PS - ultimately, I want to store my videos on a NAS (but still don't want 2GB sitcoms) - that could group series of shows, and show playlists to pull to Tivo. Right now I just got the NAS - don't know how to use it, haven't had time to post here about how to get Tivo recordings on it, etc. But after my next period of work crunch, I may devote more time to this. And that solution might incorporate my desire to keep smaller-sized recordings.
