DVR-810H - MFS mod to allow negative padding

[bdjohns1]

Mods,

Feel free to move this if S2 Development isn't the right place for this material. I just figured it out for my box, so I thought it would be good to contribute it to the knowledge base here.

Over at TCF, there's a thread (here) on modifying the strings MFS supplies in order to enable 'hard' negative padding in the TiVo UI (much like TWP does). However, for newer TiVos like my DVR-810H (running 5.2.2), the thread is outdated, as the resource locations keep changing. The script is at least useful to sniff out the correct formatting for the string you want.

We've got EndPadPlus already for when there's time available to pad recordings, but sometimes I want to make the judgement call myself to cut off a show that ends at 8:01 to record another one that starts at 8:00.

To steal from those annoying textbooks, I'll leave "how to find the right items" as an exercise for the reader, and not write a guide. (hint - look at the resource groups in /SwSystem/Active/)

For software version 5.2.2-01-2-275, the appropriate strings are in resources:

45953/31 - Start recording times
45953/33 - Stop recording times

Update the strings, flush the MFS using AlphaWolf's flushres.tcl script, reboot, and enjoy.

fsids can be different on each system (and, in the case of 5.2.2, probably are, since 5.2.2 is generally installed as an upgrade). That means that fsid 45953 on your system is probably not the same as 45953 on another system. It's also a reason why we advise people never to use "-f 9999" or "-f 4138" with mfsbackup.

For an example of how to identify and locate ResourceItems in a "portable" manner, see this thread.

The resources I suspect you are referring to are in group ID 1900544 on 5.2.2:

        Subrecord ResourceItem/30 {
                Id: 1900580
                String: {On-time\x7c0\x7c1 minute early\x7c60\x7c2 minutes early
\x7c120\x7c3 minutes early\x7c180\x7c4 minutes early\x7c240\x7c5 minutes early\x
7c300\x7c10 minutes early\x7c600\x7c}
        }

...

        Subrecord ResourceItem/32 {
                Id: 1900582
                String: {On-time\x7c0\x7c1 minute longer\x7c60\x7c2 minutes long
er\x7c120\x7c5 minutes longer\x7c300\x7c15 minutes longer\x7c900\x7c30 minutes l
onger\x7c1800\x7c1 hour longer\x7c3600\x7c1 1/2 hours longer\x7c5400\x7c3 hours 
longer\x7c10800\x7c}
        }

ADH,

Thanks for the link. You're right - they are in 1900544. I found mine by digging through the MFS in TWP as opposed to telnetting in (since I was outside my firewall and I've got an HTTPS proxy to TWP), so I just changed by the item ID. Obviously, unless you like living dangerously (and/or dumb) , you're going to do a 'dbget' beforehand in a shell to ensure you're playing with the right item. They were in something completely different in 3.x and 4.x units, based on the scripts people had ginned up at TCF.

However, as the post mentions, some of those group IDs could even change between major versions, so I might have to go fishing when I get a 7.x upgrade.

A naive hexedit might suffice. If not, time to get back to work on the brf files:
